远程 Oracle Linux 6 主机上安装的程序包受到 ELSA-2018-1854 公告中提及的多个漏洞的影响。

  - 在 4.8.11 及之前的 Linux 内核中，lib/mpi/mpi-pow.c 的 mpi_powm 函数未确保为碎片数据分配内存，这允许本地用户通过具有零指数的 RSA 密钥的 add_key 系统调用造成拒绝服务（堆栈内存损坏和错误）。(CVE-2016-8650)

  - 在低于 4.9.7 的 Linux 内核版本中，kernel/events/core.c 中存在争用条件，本地用户可利用此漏洞，通过构建的应用程序进行并发 perf_event_open 系统调用，将软件组移至硬件环境，从而获取权限。注意：存在此漏洞的原因是未完整修复 CVE-2016-6786。(CVE-2017-6001)

  - 在 Linux 内核 4.10.15 及之前版本中，攻击者可利用 net/ipv4/inet_connection_sock.c 中的 inet_csk_clone_lock 函数，通过使用接受系统调用，造成拒绝服务（双重释放），或可能造成其他不明影响。(CVE-2017-8890)

  - 在 Linux 内核 4.10.6 及之前版本中，net/packet/af_packet.c 中的 packet_set_ring 函数未正确验证特定块大小数据，本地用户可利用此漏洞，通过构建的系统调用，造成拒绝服务（整数符号错误和越界写入），或者获取权限（如果有 CAP_NET_RAW 功能）。(CVE-2017-7308)

  - 在 Linux 内核 4.11.1 及之前版本中，net/ipv6/tcp_ipv6.c 中的 tcp_v6_syn_recv_sock 函数未正确处理继承，本地用户可利用此漏洞，通过构建的系统调用，造成拒绝服务，或可能造成其他不明影响，此问题与 CVE-2017-8890 相关。(CVE-2017-9077)

  - 在 4.10.8 及之前的 Linux 内核中，net/ipv4/ping.c 中的 ping_unhash 函数在获取特定锁定出现延迟，因此无法确保断开连接函数调用的安全性，这允许本地用户利用套接字系统调用中 IPPROTO_ICMP 协议值的访问权限造成拒绝服务（错误）。(CVE-2017-2671)

  - 在 4.10.9 及之前的 Linux 内核中，在 mm/mempolicy.c 的 set_mempolicy() 和 mbind() compat 系统调用中，不正确的错误处理允许本地用户通过触发特定位图操作失败，从未初始化的堆栈数据获取敏感信息。(CVE-2017-7616)

  - 在 3.2 及之前的 Linux 内核中，mm 子系统未正确执行 CONFIG_STRICT_DEVMEM 保护机制，这使得本地用户能够通过与 arch/x86/mm/init.c 和 drivers/char/mem.c 相关的能够打开 /dev/mem 文件的应用程序读取或写入第一个兆字节中的内核内存位置（并绕过 slab-allocation 访问权限限制）。(CVE-2017-7889)

  - 在 4.11.1 及之前的 Linux 内核的 net/dccp/ipv6.c 中，dccp_v6_request_recv_sock 函数未正确处理继承，进而允许本地用户通过特制的系统调用，造成拒绝服务，或可能造成其他不明影响，此问题可能与 CVE-2017-8890 有关。(CVE-2017-9076)

  - 在 4.11.1 及之前的 Linux 内核的 net/sctp/ipv6.c 中，sctp_v6_create_accept_sk 函数未正确处理继承，进而允许本地用户通过特制的系统调用，造成拒绝服务，或可能造成其他不明影响，这是与 CVE-2017-8890 相关的问题。(CVE-2017-9075)

  - 在低于 4.13.8 的 Linux 内核版本中，当 SCSI I/O 向量具有属于相同页面的小型连续缓冲区时，block/bio.c 中的 bio_map_user_iov 和 bio_unmap_user 函数会进行不平衡的引用计数。
    bio_add_pc_page 函数会将其合并成一个，但该页面引用再也不会删除。此漏洞可能会造成内存泄露，并可能造成系统锁定（如果 SCSI 磁盘传递到虚拟机，则客户机操作系统用户可以利用主机操作系统攻击），这是内存不足所致。(CVE-2017-12190)

  - 如果应用程序在文件中打洞，其结尾未与页面边界对齐，则非特权用户能够在 RHEL 6 或 7 上挂载 fuse 文件系统，并造成系统崩溃。(CVE-2017-15121)

The 4.10.17 stable kernel update contains a number of important fixes across the tree.

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

According to the versions of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities :

  - The tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c in the Linux kernel mishandles     inheritance, which allows local users to cause a denial     of service or possibly have unspecified other impact     via crafted system calls, a related issue to     CVE-2017-8890. An unprivileged local user could use     this flaw 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 we believe it is unlikely.

  - The IPv6 DCCP implementation in the Linux kernel     mishandles inheritance, which allows local users to     cause a denial of service or possibly have unspecified     other impact via crafted system calls, a related issue     to CVE-2017-8890. An unprivileged local user could use     this flaw 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 we believe it is unlikely.

  - The sctp_v6_create_accept_sk function in     net/sctp/ipv6.c in the Linux kernel mishandles     inheritance, which allows local users to cause a denial     of service or possibly have unspecified other impact     via crafted system calls, a related issue to     CVE-2017-8890. An unprivileged local user could use     this flaw 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 we believe it is unlikely.

  - The IPv6 fragmentation implementation in the Linux     kernel through 4.11.1 does not consider that the     nexthdr field may be associated with an invalid option,     which allows local users to cause a denial of service     (out-of-bounds read and BUG) or possibly have     unspecified other impact via crafted socket and send     system calls.

  - The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allows attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call. An     unprivileged local user could use this flaw 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 we     believe it is unlikely.

  - Improved isolation for neighbor table settings. (The     fix added to the 042stab120.19 kernel was incomplete.)

    (CVE-2017-9075)

  - The IPv6 DCCP implementation in the Linux kernel     mishandles inheritance, which allows local users to     cause a denial of service or possibly have unspecified     other impact via crafted system calls, a related issue     to CVE-2017-8890.

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

The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.74 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2017-1000365: The Linux Kernel imposes a size     restriction on the arguments and environmental strings     passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the     size), but did not take the argument and environment     pointers into account, which allowed attackers to bypass     this limitation. (bnc#1039354).

  - CVE-2017-1000380: sound/core/timer.c in the Linux kernel     is vulnerable to a data race in the ALSA /dev/snd/timer     driver resulting in local users being able to read     information belonging to other users, i.e.,     uninitialized memory contents may be disclosed when a     read and an ioctl happen at the same time (bnc#1044125).

  - CVE-2017-7346: The vmw_gb_surface_define_ioctl function     in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not validate certain levels data, which     allowed local users to cause a denial of service (system     hang) via a crafted ioctl call for a /dev/dri/renderD*     device (bnc#1031796).

  - CVE-2017-9242: The __ip6_append_data function in     net/ipv6/ip6_output.c in the Linux kernel is too late in     checking whether an overwrite of an skb data structure     may occur, which allowed local users to cause a denial     of service (system crash) via crafted system calls     (bnc#1041431).

  - CVE-2017-9076: The dccp_v6_request_recv_sock function in     net/dccp/ipv6.c in the Linux kernel mishandled     inheritance, which allowed local users to cause a denial     of service or possibly have unspecified other impact via     crafted system calls, a related issue to CVE-2017-8890     (bnc#1039885).

  - CVE-2017-9077: The tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c in the Linux kernel mishandled     inheritance, which allowed local users to cause a denial     of service or possibly have unspecified other impact via     crafted system calls, a related issue to CVE-2017-8890     (bnc#1040069).

  - CVE-2017-9075: The sctp_v6_create_accept_sk function in     net/sctp/ipv6.c in the Linux kernel mishandled     inheritance, which allowed local users to cause a denial     of service or possibly have unspecified other impact via     crafted system calls, a related issue to CVE-2017-8890     (bnc#1039883).

  - CVE-2017-9074: The IPv6 fragmentation implementation in     the Linux kernel did not consider that the nexthdr field     may be associated with an invalid option, which allowed     local users to cause a denial of service (out-of-bounds     read and BUG) or possibly have unspecified other impact     via crafted socket and send system calls (bnc#1039882).

  - CVE-2017-8924: The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel allowed     local users to obtain sensitive information (in the     dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an io_ti     USB serial device) to trigger an integer underflow.
    (bsc#1038982)

  - CVE-2017-8925: The omninet_open function in     drivers/usb/serial/omninet.c in the Linux kernel allowed     local users to cause a denial of service (tty     exhaustion) by leveraging reference count mishandling.
    (bsc#1038981)

  - CVE-2017-7487: The ipxitf_ioctl function in     net/ipx/af_ipx.c in the Linux kernel mishandled     reference counts, which allowed local users to cause a     denial of service (use-after-free) or possibly have     unspecified other impact via a failed SIOCGIFADDR ioctl     call for an IPX interface (bnc#1038879).

  - CVE-2017-8890: The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allowed attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call (bnc#1038544).

  - CVE-2017-9150: The do_check function in     kernel/bpf/verifier.c in the Linux kernel did not make     the allow_ptr_leaks value available for restricting the     output of the print_bpf_insn function, which allowed     local users to obtain sensitive address information via     crafted bpf system calls (bnc#1040279).

  - CVE-2017-7618: crypto/ahash.c in the Linux kernel     allowed attackers to cause a denial of service (API     operation calling its own callback, and infinite     recursion) by triggering EBUSY on a full queue     (bnc#1033340).

  - CVE-2017-7616: Incorrect error handling in the     set_mempolicy and mbind compat syscalls in     mm/mempolicy.c in the Linux kernel allowed local users     to obtain sensitive information from uninitialized stack     data by triggering failure of a certain bitmap operation     (bnc#1033336).

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1842 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP     Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system.
    (CVE-2016-10200, Important)

    * A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A     local user could use this flaw to crash the system or, potentially, escalate their privileges.
    (CVE-2017-2647, Important)

    * It was found that the NFSv4 server in the Linux kernel did not properly validate layout type when     processing NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A remote attacker could use this flaw to soft-     lockup the system and thus cause denial of service. (CVE-2017-8797, Important)

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-1842 advisory.

  - The do_umount function in fs/namespace.c in the Linux kernel through 3.17 does not require the     CAP_SYS_ADMIN capability for do_remount_sb calls that change the root filesystem to read-only, which     allows local users to cause a denial of service (loss of writability) by making certain unshare system     calls, clearing the / MNT_LOCKED flag, and making an MNT_FORCE umount system call. (CVE-2014-7975)

  - The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU     Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout     data, which allows local users to cause a denial of service (stack memory corruption and panic) by reading     the /proc/keys file. (CVE-2016-7042)

  - Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel before 4.6.3     allows local users to cause a denial of service (double free) or possibly have unspecified other impact     via a crafted application that makes sendmsg system calls, leading to a free operation associated with a     new dump that started earlier than anticipated. (CVE-2016-9806)

  - The blk_rq_map_user_iov function in block/blk-map.c in the Linux kernel before 4.8.14 does not properly     restrict the type of iterator, which allows local users to read or write to arbitrary kernel memory     locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device.
    (CVE-2016-9576)

  - The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in     situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary     kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg     device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an     incomplete fix for CVE-2016-9576. (CVE-2016-10088)

  - The filesystem implementation in the Linux kernel through 4.8.2 preserves the setgid bit during a setxattr     call, which allows local users to gain group privileges by leveraging the existence of a setgid program     with restrictions on execute permissions. (CVE-2016-7097)

  - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause     a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large     command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write     function. (CVE-2017-7187)

  - crypto/mcryptd.c in the Linux kernel before 4.8.15 allows local users to cause a denial of service (NULL     pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as     demonstrated by mcryptd(md5). (CVE-2016-10147)

  - arch/x86/kvm/vmx.c in the Linux kernel through 4.9 mismanages the #BP and #OF exceptions, which allows     guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by     an L2 guest. (CVE-2016-9588)

  - The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly     emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS     memory consumption) by leveraging the mishandling of page references. (CVE-2017-2596)

  - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to     cause a denial of service (system crash) via a crafted application that makes sendto system calls, related     to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)

  - The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows     attackers to cause a denial of service (system crash) via (1) an application that makes crafted system     calls or possibly (2) IPv4 traffic with invalid IP options. (CVE-2017-5970)

  - Race condition in kernel/events/core.c in the Linux kernel before 4.9.7 allows local users to gain     privileges via a crafted application that makes concurrent perf_event_open system calls for moving a     software group into a hardware context. NOTE: this vulnerability exists because of an incomplete fix for     CVE-2016-6786. (CVE-2017-6001)

  - The KEYS subsystem in the Linux kernel before 3.18 allows local users to gain privileges or cause a denial     of service (NULL pointer dereference and system crash) via vectors involving a NULL value for a certain     match field, related to the keyring_search_iterator function in keyring.c. (CVE-2017-2647)

  - The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel through 4.10.15     allows attackers to cause a denial of service (double free) or possibly have unspecified other impact by     leveraging use of the accept system call. (CVE-2017-8890)

  - The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel through 4.11.1 mishandles     inheritance, which allows local users to cause a denial of service or possibly have unspecified other     impact via crafted system calls, a related issue to CVE-2017-8890. (CVE-2017-9077)

  - The pivot_root implementation in fs/namespace.c in the Linux kernel through 3.17 does not properly     interact with certain locations of a chroot directory, which allows local users to cause a denial of     service (mount-tree loop) via . (dot) values in both arguments to the pivot_root system call.
    (CVE-2014-7970)

  - crypto/algif_skcipher.c in the Linux kernel before 4.4.2 does not verify that a setkey operation has been     performed on an AF_ALG socket before an accept system call is processed, which allows local users to cause     a denial of service (NULL pointer dereference and system crash) via a crafted application that does not     supply a key, related to the lrw_crypt function in crypto/lrw.c. (CVE-2015-8970)

  - Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel before 4.8.14 allows local users     to gain privileges or cause a denial of service (use-after-free) by making multiple bind system calls     without properly ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c     and net/l2tp/l2tp_ip6.c. (CVE-2016-10200)

  - fs/namespace.c in the Linux kernel before 4.9 does not restrict how many mounts may exist in a mount     namespace, which allows local users to cause a denial of service (memory consumption and deadlock) via     MS_BIND mount system calls, as demonstrated by a loop that triggers exponential growth in the number of     mounts. (CVE-2016-6213)

  - It was discovered in the Linux kernel before 4.11-rc8 that root can gain direct access to an internal     keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its     session keyring. This allows root to bypass module signature verification by adding a new public key of     its own devising to the keyring. (CVE-2016-9604)

  - The ping_unhash function in net/ipv4/ping.c in the Linux kernel through 4.10.8 is too late in obtaining a     certain lock and consequently cannot ensure that disconnect function calls are safe, which allows local     users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a     socket system call. (CVE-2017-2671)

  - The keyring_search_aux function in security/keys/keyring.c in the Linux kernel through 3.14.79 allows     local users to cause a denial of service (NULL pointer dereference and OOPS) via a request_key system call     for the dead type. (CVE-2017-6951)

  - Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux     kernel through 4.10.9 allows local users to obtain sensitive information from uninitialized stack data by     triggering failure of a certain bitmap operation. (CVE-2017-7616)

  - The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM     protection mechanism, which allows local users to read or write to kernel memory locations in the first     megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file,     related to arch/x86/mm/init.c and drivers/char/mem.c. (CVE-2017-7889)

  - The IPv6 fragmentation implementation in the Linux kernel through 4.11.1 does not consider that the     nexthdr field may be associated with an invalid option, which allows local users to cause a denial of     service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send     system calls. (CVE-2017-9074)

  - The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux kernel through 4.11.1 mishandles     inheritance, which allows local users to cause a denial of service or possibly have unspecified other     impact via crafted system calls, a related issue to CVE-2017-8890. (CVE-2017-9076)

  - The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel through 4.11.3 is too late in     checking whether an overwrite of an skb data structure may occur, which allows local users to cause a     denial of service (system crash) via crafted system calls. (CVE-2017-9242)

  - Multiple race conditions in the ext4 filesystem implementation in the Linux kernel before 4.5 allow local     users to cause a denial of service (disk corruption) by writing to a page that is associated with a     different user's file after unsynchronized hole punching and page-fault handling. (CVE-2015-8839)

  - Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel before 4.5.1 allow     local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations.
    (CVE-2016-9685)

  - The NFSv4 server in the Linux kernel before 4.11.3 does not properly validate the layout type when     processing the NFSv4 pNFS GETDEVICEINFO or LAYOUTGET operand in a UDP packet from a remote attacker. This     type value is uninitialized upon encountering certain error conditions. This value is used as an array     index for dereferencing, which leads to an OOPS and eventually a DoS of knfsd and a soft-lockup of the     whole system. (CVE-2017-8797)

  - The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel through 4.11.1 mishandles     inheritance, which allows local users to cause a denial of service or possibly have unspecified other     impact via crafted system calls, a related issue to CVE-2017-8890. (CVE-2017-9075)

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

The remote Oracle Linux host is missing a security update for the kernel package(s).

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2018-0015 for details.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):Use-after-free     vulnerability in driverset/tun.c in the Linux kernel     through 3.11.1 allows local users to gain privileges by     leveraging the CAP_NET_ADMIN capability and providing     an invalid tuntap interface name in a TUNSETIFF ioctl     call.(CVE-2013-4343)It was found that when the gcc     stack protector was enabled, reading the /proc/keys     file could cause a panic in the Linux kernel due to     stack corruption. This happened because an incorrect     buffer size was used to hold a 64-bit timeout value     rendered as weeks.(CVE-2016-7042)A flaw was found in     the Linux kernel that fs/ocfs2/aops.c omits use of a     semaphore and consequently has a race condition for     access to the extent tree during read operations in     DIRECT mode. This allows local users to cause a denial     of service by modifying a certain e_cpos     field.(CVE-2017-18224)The sctp_v6_create_accept_sk     function in net/sctp/ipv6.c in the Linux kernel     mishandles inheritance, which allows local users to     cause a denial of service or possibly have unspecified     other impact via crafted system calls, a related issue     to CVE-2017-8890. An unprivileged local user could use     this flaw 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 we believe it is unlikely.(CVE-2017-9075)In     the function sbusfb_ioctl_helper() in     drivers/video/fbdev/sbuslib.c in the Linux kernel, up     to and including 4.15, an integer signedness error     allows arbitrary information leakage for the     FBIOPUTCMAP_SPARC and FBIOGETCMAP_SPARC     commands.(CVE-2018-6412)A race condition flaw was found     in the way the Linux kernel's mmap(2), madvise(2), and     fallocate(2) system calls interacted with each other     while operating on virtual memory file system files. A     local user could use this flaw to cause a denial of     service.(CVE-2014-4171)** RESERVED ** This candidate     has been reserved by an organization or individual that     will use it when announcing a new security problem.
    When the candidate has been publicized, the details for     this candidate will be provided.(CVE-2018-1095)A NULL     pointer dereference flaw was found in the way the Linux     kernel's Stream Control Transmission Protocol (SCTP)     implementation handled simultaneous connections between     the same hosts. A remote attacker could use this flaw     to crash the system.(CVE-2014-5077)A vulnerability was     found in the fs/inode.c:inode_init_owner() function     logic of the LInux kernel that allows local users to     create files with an unintended group ownership and     with group execution and SGID permission bits set, in a     scenario where a directory is SGID and belongs to a     certain group and is writable by a user who is not a     member of this group. This can lead to excessive     permissions granted in case when they should     not.(CVE-2018-13405)In the Linux kernel before 4.20.8,     kvm_ioctl_create_device in virt/kvm/kvm_main.c     mishandles reference counting because of a race     condition, leading to a use-after-free.(CVE-2019-6974)A     flaw was found in the way Linux kernel allocates heap     memory to build the scattergather list from a fragment     list(skb_shinfo(skb)-i1/4zfrag_list) in the socket     buffer(skb_buff). The heap overflow occurred if     'MAX_SKB_FRAGS + 1' parameter and 'NETIF_F_FRAGLIST'     feature are both used together. A remote user or     process could use this flaw to potentially escalate     their privilege on a system.(CVE-2017-7477)Multiple     integer overflows in Alchemy LCD frame-buffer drivers     in the Linux kernel before 3.12 allow local users to     create a read-write memory mapping for the entirety of     kernel memory, and consequently gain privileges, via     crafted mmap operations, related to the (1)     au1100fb_fb_mmap function in drivers/video/au1100fb.c     and the (2) au1200fb_fb_mmap function in     drivers/video/au1200fb.c.(CVE-2013-4511)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)An issue was discovered in     the Linux kernel before 4.19.3. crypto_report_one() and     related functions in crypto/crypto_user.c (the crypto     user configuration API) do not fully initialize     structures that are copied to userspace, potentially     leaking sensitive memory to user programs. NOTE: this     is a CVE-2013-2547 regression but with easier     exploitability because the attacker does not need a     capability (however, the system must have the     CONFIG_CRYPTO_USER kconfig option).(CVE-2018-19854)The     userfaultfd implementation in the Linux kernel before     4.19.7 mishandles access control for certain UFFDIO_     ioctl calls, as demonstrated by allowing local users to     write data into holes in a tmpfs file (if the user has     read-only access to that file, and that file contains     holes), related to fs/userfaultfd.c and     mm/userfaultfd.c.(CVE-2018-18397)The TCP stack in the     Linux kernel through 4.10.6 mishandles the     SCM_TIMESTAMPING_OPT_STATS feature, which allows local     users to obtain sensitive information from the kernel's     internal socket data structures or cause a denial of     service (out-of-bounds read) via crafted system calls,     related to net/core/skbuff.c and     net/socket.c.(CVE-2017-7277)A flaw was found in the way     the Linux kernel's vhost driver treated userspace     provided log file descriptor when processing the     VHOST_SET_LOG_FD ioctl command. The file descriptor was     never released and continued to consume kernel memory.
    A privileged local user with access to the     /dev/vhost-net files could use this flaw to create a     denial-of-service attack.(CVE-2015-6252)A buffer     overflow flaw was found in the way the Linux kernel's     virtio-net subsystem handled certain fraglists when the     GRO (Generic Receive Offload) functionality was enabled     in a bridged network configuration. An attacker on the     local network could potentially use this flaw to crash     the system, or, although unlikely, elevate their     privileges on the system.(CVE-2015-5156)The MSM QDSP6     audio driver (aka sound driver) for the Linux kernel     3.x, as used in Qualcomm Innovation Center (QuIC)     Android contributions for MSM devices and other     products, allows attackers to gain privileges or cause     a denial of service (integer overflow, and buffer     overflow or buffer over-read) via a crafted application     that performs a (1) AUDIO_EFFECTS_WRITE or (2)     AUDIO_EFFECTS_READ operation, aka Qualcomm internal bug     CR1006609.(CVE-2016-2068)The icmp6_send function in     net/ipv6/icmp.c in the Linux kernel through 4.8.12     omits a certain check of the dst data structure which     allows remote attackers to cause a denial of service     (panic) via a fragmented IPv6 packet.(CVE-2016-9919)
