The SUSE Linux Enterprise 12 SP3 kernel for Azure was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic was uninitialized (bnc#1116841).

CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bnc#1120743).

CVE-2018-3639: Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4 (bnc#1087082).

CVE-2018-1120: By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which made a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks) (bnc#1093158). </pid></pid>

CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages (bnc#1069702).

CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946).

CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714).

CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation (bnc#1118319).

CVE-2018-16862: A security flaw was found in the way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one (bnc#1117186).

CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).

The update package also includes non-security fixes. See advisory for details.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2948 advisory.

    The kernel-alt packages provide the Linux kernel version 4.x.

    Security Fix(es):

    * An industry-wide issue was found in the way many modern microprocessor designs have implemented     speculative execution of Load & Store instructions (a commonly used performance optimization). It relies     on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact     that memory read from address to which a recent memory write has occurred may see an older value and     subsequently cause an update into the microprocessor's data cache even for speculatively executed     instructions that never actually commit (retire). As a result, an unprivileged attacker could use this     flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639, aarch64)

    * A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A     remote attacker could use this flaw to trigger time and calculation expensive calls to     tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within     ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system.
    Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open     port, thus the attacks cannot be performed using spoofed IP addresses. (CVE-2018-5390)

    * A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4     and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment     reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a     denial of service on the system. (CVE-2018-5391)

New kernel packages are available for Slackware 14.2 to fix security issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a     process's memory containing command line arguments (or environment strings), an attacker can cause     utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the     /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some     controlled time (as a synchronization primitive for other attacks). (CVE-2018-1120)

Note that Nessus relies on the presence of the package as reported by the vendor.

Linux 4.9 has been packaged for Debian 8 as linux-4.9. This provides a supported upgrade path for systems that currently use kernel packages from the 'jessie-backports' suite.

There is no need to upgrade systems using Linux 3.16, as that kernel version will also continue to be supported in the LTS period.

This backport does not include the following binary packages :

hyperv-daemons libcpupower1 libcpupower-dev libusbip-dev linux-compiler-gcc-4.9-x86 linux-cpupower linux-libc-dev usbip

Older versions of most of those are built from other source packages in Debian 8.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2017-5753

Further instances of code that was vulnerable to Spectre variant 1 (bounds-check bypass) have been mitigated.

CVE-2017-18255

It was discovered that the performance events subsystem did not properly validate the value of the kernel.perf_cpu_time_max_percent sysctl. Setting a large value could have an unspecified security impact. However, only a privileged user can set this sysctl.

CVE-2018-1118

The syzbot software found that the vhost driver did not initialise message buffers which would later be read by user processes. A user with access to the /dev/vhost-net device could use this to read sensitive information from the kernel or other users' processes.

CVE-2018-1120

Qualys reported that a user able to mount FUSE filesystems can create a process such that when another process attempting to read its command line will be blocked for an arbitrarily long time. This could be used for denial of service, or to aid in exploiting a race condition in the other program.

CVE-2018-1130

The syzbot software found that the DCCP implementation of sendmsg() does not check the socket state, potentially leading to a NULL pointer dereference. A local user could use this to cause a denial of service (crash). 

CVE-2018-3639

Multiple researchers have discovered that Speculative Store Bypass (SSB), a feature implemented in many processors, could be used to read sensitive information from another context. In particular, code in a software sandbox may be able to read sensitive information from outside the sandbox. This issue is also known as Spectre variant 4.

This update allows the issue to be mitigated on some x86 processors by disabling SSB. This requires an update to the processor's microcode, which is non-free. It may be included in an update to the system BIOS or UEFI firmware, or in a future update to the intel-microcode or amd64-microcode packages.

Disabling SSB can reduce performance significantly, so by default it is only done in tasks that use the seccomp feature. Applications that require this mitigation should request it explicitly through the prctl() system call. Users can control where the mitigation is enabled with the spec_store_bypass_disable kernel parameter.

CVE-2018-5814

Jakub Jirasek reported race conditions in the USB/IP host driver. A malicious client could use this to cause a denial of service (crash or memory corruption), and possibly to execute code, on a USB/IP server.

CVE-2018-10021

A physically present attacker who unplugs a SAS cable can cause a denial of service (memory leak and WARN).

CVE-2018-10087, CVE-2018-10124

zhongjiang found that the wait4() and kill() system call implementations did not check for the invalid pid value of INT_MIN. If a user passed this value, the behaviour of the code was formally undefined and might have had a security impact.

CVE-2018-10853

Andy Lutomirski and Mika Penttil&auml; reported that KVM for x86 processors did not perform a necessary privilege check when emulating certain instructions. This could be used by an unprivileged user in a guest VM to escalate their privileges within the guest.

CVE-2018-10876, CVE-2018-10877, CVE-2018-10878, CVE-2018-10879, CVE-2018-10880, CVE-2018-10881, CVE-2018-10882, CVE-2018-10883

Wen Xu at SSLab, Gatech, reported that crafted ext4 filesystem images could trigger a crash or memory corruption. A local user able to mount arbitrary filesystems, or an attacker providing filesystems to be mounted, could use this for denial of service or possibly for privilege escalation.

CVE-2018-10940

Dan Carpenter reported that the optical disc driver (cdrom) does not correctly validate the parameter to the CDROM_MEDIA_CHANGED ioctl. A user with access to a cdrom device could use this to cause a denial of service (crash).

CVE-2018-11506

Piotr Gabriel Kosinski and Daniel Shapira reported that the SCSI optical disc driver (sr) did not allocate a sufficiently large buffer for sense data. A user with access to a SCSI optical disc device that can produce more than 64 bytes of sense data could use this to cause a denial of service (crash or memory corruption), and possibly for privilege escalation.

CVE-2018-12233

Shankara Pailoor reported that a crafted JFS filesystem image could trigger a denial of service (memory corruption). This could possibly also be used for privilege escalation.

CVE-2018-1000204

The syzbot software found that the SCSI generic driver (sg) would in some circumstances allow reading data from uninitialised buffers, which could include sensitive information from the kernel or other tasks. However, only privileged users with the CAP_SYS_ADMIN or CAP_SYS_RAWIO capability were allowed to do this, so this has little or no security impact.

For Debian 8 'Jessie', these problems have been fixed in version 4.9.110-1~deb8u1. This update additionally fixes Debian bugs #860900, #872907, #892057, #896775, #897590, and #898137; and includes many more bug fixes from stable updates 4.9.89-4.9.110 inclusive.

We recommend that you upgrade your linux-4.9 packages.

The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.175 to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, leading to a use-after-free. (bnc#1124728)

CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM hypervisor related to the emulation of a preemption timer, allowing an guest user/process to crash the host kernel. (bsc#1124732).

CVE-2019-7222: Fixed an information leakage in the KVM hypervisor related to handling page fault exceptions, which allowed a guest user/process to use this flaw to leak the host's stack memory contents to a guest (bsc#1124735).

CVE-2018-1120: By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker could have caused utilities from psutils or procps (such as ps, w) or any other program which made a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks) (bnc#1093158).
</pid></pid>

CVE-2018-16862: A security flaw was found in a way that the cleancache subsystem clears an inode after the final file truncation (removal).
The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one (bnc#1117186).

CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946).

CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841).

CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).

CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bnc#1120743).

CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714).

CVE-2018-5391: The Linux kernel was vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bnc#1103097).

CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (bnc#1118319).

CVE-2019-3459,CVE-2019-3460: Two remote information leak vulnerabilities in the Bluetooth stack were fixed that could potentially leak kernel information (bsc#1120758)

The update package also includes non-security fixes. See advisory for details.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - In the Linux kernel before 4.13.5, a local user could     create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of     service.(CVE-2017-18270)

  - ** DISPUTED ** Linux Kernel version 3.18 to 4.16     incorrectly handles an SG_IO ioctl on /dev/sg0 with     dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte     cmdp. This may lead to copying up to 1000 kernel heap     pages to the userspace. This has been fixed upstream in     https://github.com/torvalds/linux/commit/a45b599ad808c3     c982fdcdc12b0b8611c2f92824 already. The problem has     limited scope, as users don't usually have permissions     to access SCSI devices. On the other hand, e.g. the     Nero user manual suggests doing `chmod o+r+w /dev/sg*`     to make the devices accessible.(CVE-2018-1000204)

  - A flaw was found affecting the Linux kernel before     version 4.17. By mmap()ing a FUSE-backed file onto a     process's memory containing command line arguments (or     environment strings), an attacker can cause utilities     from psutils or procps (such as ps, w) or any other     program which makes a read() call to the     /proc/pid/cmdline (or /proc/pid/environ) files to block     indefinitely (denial of service) or for some controlled     time (as a synchronization primitive for other     attacks).(CVE-2018-1120)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003276 advisory.

    A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a     process's memory containing command line arguments (or environment strings), an attacker can cause     utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the     /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some     controlled time (as a synchronization primitive for other attacks).

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities:

  - Integer overflow in the aio_setup_single_vector function     in fs/aio.c in the Linux kernel 4.0 allows local users     to cause a denial of service or possibly have     unspecified other impact via a large AIO iovec. NOTE:
    this vulnerability exists because of a CVE-2012-6701     regression. (CVE-2015-8830)

  - A weakness was found in the Linux ASLR implementation.
    Any user able to running 32-bit applications in a x86     machine can disable ASLR by setting the RLIMIT_STACK     resource to unlimited. (CVE-2016-3672)

  - The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) via vectors     involving omission of the firmware name from a certain     data structure. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely. (CVE-2016-7913)

  - Use-after-free vulnerability in the snd_pcm_info()     function in the ALSA subsystem in the Linux kernel     allows attackers to induce a kernel memory corruption     and possibly crash or lock up a system. Due to the     nature of the flaw, a privilege escalation cannot be     fully ruled out, although we believe it is unlikely.
    (CVE-2017-0861)

  - A reachable assertion failure flaw was found in the     Linux kernel built with KVM virtualisation(CONFIG_KVM)     support with Virtual Function I/O feature (CONFIG_VFIO)     enabled. This failure could occur if a malicious guest     device sent a virtual interrupt (guest IRQ) with a     larger (>1024) index value. (CVE-2017-1000252)

  - Linux kernel Virtualization Module (CONFIG_KVM) for the     Intel processor family (CONFIG_KVM_INTEL) is vulnerable     to a DoS issue. It could occur if a guest was to flood     the I/O port 0x80 with write requests. A guest user     could use this flaw to crash the host kernel resulting     in DoS. (CVE-2017-1000407)

  - A flaw was found in the processing of incoming L2CAP     bluetooth commands. Uninitialized stack variables can be     sent to an attacker leaking data in kernel address     space. (CVE-2017-1000410)

  - A race condition was found in the Linux kernel before     version 4.11-rc1 in 'fs/timerfd.c' file which allows a     local user to cause a kernel list corruption or use-     after-free via simultaneous operations with a file     descriptor which leverage improper 'might_cancel'     queuing. An unprivileged local user could use this flaw     to cause a denial of service of the system. Due to the     nature of the flaw, privilege escalation cannot be fully     ruled out, although we believe it is unlikely.
    (CVE-2017-10661)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization (nVMX) feature     enabled (nested=1), is vulnerable to a crash due to     disabled external interrupts. As L2 guest could access     (r/w) hardware CR8 register of the host(L0). In a nested     visualization setup, L2 guest user could use this flaw     to potentially crash the host(L0) resulting in DoS.
    (CVE-2017-12154)

  - It was found that in the Linux kernel through v4.14-rc5,     bio_map_user_iov() and bio_unmap_user() in 'block/bio.c'     do unbalanced pages refcounting if IO vector has small     consecutive buffers belonging to the same page.
    bio_add_pc_page() merges them into one, but the page     reference is never dropped, causing a memory leak and     possible system lockup due to out-of-memory condition.
    (CVE-2017-12190)

  - A flaw was found in the Linux kernel's implementation of     valid_master_desc() in which a memory buffer would be     compared to a userspace value with an incorrect size of     comparison. By bruteforcing the comparison, an attacker     could determine what was in memory after the description     and possibly obtain sensitive information from kernel     memory. (CVE-2017-13305)

  - A use-after-free vulnerability was found in a network     namespaces code affecting the Linux kernel since     v4.0-rc1 through v4.15-rc5. The function     get_net_ns_by_id() does not check for the net::count     value after it has found a peer network in netns_ids idr     which could lead to double free and memory corruption.
    This vulnerability could allow an unprivileged local     user to induce kernel memory corruption on the system,     leading to a crash. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out, although     it is thought to be unlikely. (CVE-2017-15129)

  - A use-after-free vulnerability was found when issuing an     ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption or     possibly privilege escalation. (CVE-2017-15265)

  - A flaw was found in the implementation of associative     arrays where the add_key systemcall and KEYCTL_UPDATE     operations allowed for a NULL payload with a nonzero     length. When accessing the payload within this length     parameters value, an unprivileged user could trivially     cause a NULL pointer dereference (kernel oops).
    (CVE-2017-15274)

  - The net/netfilter/nfnetlink_cthelper.c function in the     Linux kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for new, get, and del     operations. This allows local users to bypass intended     access restrictions because the nfnl_cthelper_list data     structure is shared across all net namespaces.
    (CVE-2017-17448)

  - The __netlink_deliver_tap_skb function in     net/netlink/af_netlink.c in the Linux kernel, through     4.14.4, does not restrict observations of Netlink     messages to a single net namespace, when CONFIG_NLMON is     enabled. This allows local users to obtain sensitive     information by leveraging the CAP_NET_ADMIN capability     to sniff an nlmon interface for all Netlink activity on     the system. (CVE-2017-17449)

  - The usb_destroy_configuration() function, in     'drivers/usb/core/config.c' in the USB core subsystem,     in the Linux kernel through 4.14.5 does not consider the     maximum number of configurations and interfaces before     attempting to release resources. This allows local users     to cause a denial of service, due to out-of-bounds write     access, or possibly have unspecified other impact via a     crafted USB device. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out, although     we believe it is unlikely. (CVE-2017-17558)

  - The Salsa20 encryption algorithm in the Linux kernel,     before 4.14.8, does not correctly handle zero-length     inputs. This allows a local attacker the ability to use     the AF_ALG-based skcipher interface to cause a denial of     service (uninitialized-memory free and kernel crash) or     have an unspecified other impact by executing a crafted     sequence of system calls that use the blkcipher_walk     API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 are     vulnerable. (CVE-2017-17805)

  - The tcpmss_mangle_packet function in     net/netfilter/xt_TCPMSS.c in the Linux kernel before     4.11, and 4.9.x before 4.9.36, allows remote attackers     to cause a denial of service (use-after-free and memory     corruption) or possibly have unspecified other impact by     leveraging the presence of xt_TCPMSS in an iptables     action. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely. (CVE-2017-18017)

  - The Linux kernel, before version 4.14.3, is vulnerable     to a denial of service in     drivers/md/dm.c:dm_get_from_kobject() which can be     caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM     devices. Only privileged local users (with CAP_SYS_ADMIN     capability) can directly perform the ioctl operations     for dm device creation and removal and this would     typically be outside the direct control of the     unprivileged attacker. (CVE-2017-18203)

  - The madvise_willneed function in the Linux kernel allows     local users to cause a denial of service (infinite loop)     by triggering use of MADVISE_WILLNEED for a DAX mapping.
    (CVE-2017-18208)

  - A flaw was found where the kernel truncated the value     used to indicate the size of a buffer which it would     later become zero using an untruncated value. This can     corrupt memory outside of the original allocation.
    (CVE-2017-9725)

  - In the Linux kernel versions 4.12, 3.10, 2.6, and     possibly earlier, a race condition vulnerability exists     in the sound system allowing for a potential deadlock     and memory corruption due to use-after-free condition     and thus denial of service. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely. (CVE-2018-1000004)

  - Improper validation in the bnx2x network card driver of     the Linux kernel version 4.15 can allow for denial of     service (DoS) attacks via a packet with a gso_size     larger than ~9700 bytes. Untrusted guest VMs can exploit     this vulnerability in the host machine, causing a crash     in the network card. (CVE-2018-1000026)

  - By mmap()ing a FUSE-backed file onto a process's memory     containing command line arguments (or environment     strings), an attacker can cause utilities from psutils     or procps (such as ps, w) or any other program which     makes a read() call to the /proc//cmdline (or     /proc//environ) files to block indefinitely (denial     of service) or for some controlled time (as a     synchronization primitive for other attacks).
    (CVE-2018-1120)

  - A null pointer dereference in dccp_write_xmit() function     in net/dccp/output.c in the Linux kernel allows a local     user to cause a denial of service by a number of certain     crafted system calls. (CVE-2018-1130)

  - An issue was discovered in the proc_pid_stack function     in fs/proc/base.c in the Linux kernel. An attacker with     a local account can trick the stack unwinder code to     leak stack contents to userspace. The fix allows only     root to inspect the kernel stack of an arbitrary task.
    (CVE-2018-17972)

  - A flaw was found in the Linux kernel with files on tmpfs     and hugetlbfs. An attacker is able to bypass file     permissions on filesystems mounted with tmpfs/hugetlbs     to modify a file and possibly disrupt normal system     behavior. At this time there is an understanding there     is no crash or privilege escalation but the impact of     modifications on these filesystems of files in     production systems may have adverse affects.
    (CVE-2018-18397)

  - In the Linux kernel before 4.17, a local attacker able     to set attributes on an xfs filesystem could make this     filesystem non-operational until the next mount by     triggering an unchecked error condition during an xfs     attribute change, because xfs_attr_shortform_addname in     fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE     operations with conversion of an attr from short to long     form. (CVE-2018-18690)

  - A flaw was found in the Linux kernel's handling of     loopback devices. An attacker, who has permissions to     setup loopback disks, may create a denial of service or     other unspecified actions. (CVE-2018-5344)

  - The acpi_smbus_hc_add function in drivers/acpi/sbshc.c     in the Linux kernel, through 4.14.15, allows local users     to obtain sensitive address information by reading dmesg     data from an SBS HC printk call. (CVE-2018-5750)

  - An error in the _sctp_make_chunk() function     (net/sctp/sm_make_chunk.c) when handling SCTP, packet     length can be exploited by a malicious local user to     cause a kernel crash and a DoS. (CVE-2018-5803)

  - In the function wmi_set_ie() in the Linux kernel the     length validation code does not handle unsigned integer     overflow properly. As a result, a large value of the     ie_len argument can cause a buffer overflow and thus a     memory corruption leading to a system crash or other or     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out, although     we believe it is unlikely. (CVE-2018-5848)

  - ALSA sequencer core initializes the event pool on demand     by invoking snd_seq_pool_init() when the first write     happens and the pool is empty. A user can reset the pool     size manually via ioctl concurrently, and this may lead     to UAF or out-of-bound access. (CVE-2018-7566)

  - A possible memory corruption due to a type confusion was     found in the Linux kernel in the sk_clone_lock()     function in the net/core/sock.c. The possibility of     local escalation of privileges cannot be fully ruled out     for a local unprivileged attacker. (CVE-2018-9568)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
