    A denial of service flaw for virtual machine guests in the Linux kernel's Xen hypervisor subsystem was     found in the way users call some interrupts with high frequency from one of the guests.A local user could     use this flaw to starve the resources resulting in a denial of service. (CVE-2021-28713)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: The timeout could even never trigger if the guest manages to have only one free     slot in its RX queue ring page and the next package would require more than one free slot, which may be     the case when using GSO, XDP, or software hashing. (CVE-2021-28714)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715)

    A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

    A flaw memory leak in the Linux kernel's eBPF for the Simulated networking device driver in the way user     uses BPF for the device such that function nsim_map_alloc_elem being called. A local user could use this     flaw to get unauthorized access to some data. (CVE-2021-4135)

    A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size     increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS     filesystem otherwise not accessible to them. (CVE-2021-4155)

    An out-of-bounds write flaw was found in the Linux kernel's Aquantia AQtion Ethernet card Atlantic driver     in the way the ethernet card provides malicious input to the driver. This flaw allows a local user to     emulate the networking device and crash the system. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2021-43975)

(CVE-2022-0185)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

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

  - A double free bug in packet_set_ring() in net/packet/af_packet.c can be exploited by a local user through     crafted syscalls to escalate privileges or deny service. We recommend upgrading kernel past the effected     versions or rebuilding past ec6af094ea28f0f2dda1a6a33b14cd57e36a9755 (CVE-2021-22600)

  - An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations     often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success     or failure of each one is reported to the backend driver, and the backend driver then loops over the     results, performing follow-up actions based on the success or failure of each operation. Unfortunately,     when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively     implying their success from the success of related batch elements. In other cases, errors resulting from     one batch element lead to further batch elements not being inspected, and hence successful ones to not be     possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are     vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. This affects arch/*/xen/p2m.c and     drivers/xen/gntdev.c. (CVE-2021-26932)

  - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the     ability to run PV backends in regular unprivileged guests, typically referred to as 'driver domains'.
    Running PV backends in driver domains has one primary security advantage: if a driver domain gets     compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain     could try to attack other guests via sending events at a high frequency leading to a Denial of Service in     the guest due to trying to service interrupts for elongated amounts of time. There are three affected     backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch     3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)

  - An Out-of-Bounds Read was discovered in arch/arm/mach-footbridge/personal-pci.c in the Linux kernel     through 5.12.11 because of the lack of a check for a value that shouldn't be negative, e.g., access to     element -2 of an array, aka CID-298a58e165e4. (CVE-2021-32078)

  - In gre_handle_offloads of ip_gre.c, there is a possible page fault due to an invalid memory access. This     could lead to local information disclosure with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-150694665References: Upstream kernel (CVE-2021-39633)

  - In various setup methods of the USB gadget subsystem, there is a possible out of bounds write due to an     incorrect flag check. This could lead to local escalation of privilege with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-210292376References: Upstream kernel (CVE-2021-39685)

  - An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in     the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could     potentially use this flaw to crash the system or escalate privileges on the system. (CVE-2021-4157)

  - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

  - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and     SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a     user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)

  - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.
    This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory     object. (CVE-2021-44733)

  - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information     leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based     attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)

  - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak     because the hash table is very small. (CVE-2021-45486)

  - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network     protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more     buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)

  - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the     way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or     escalate their privileges on the system. (CVE-2022-0330)

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5096 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation,     denial of service or information leaks. CVE-2020-29374 Jann Horn of Google reported a flaw in Linux's     virtual memory management. A parent and child process initially share all their memory, but when either     writes to a shared page, the page is duplicated and unshared (copy-on-write). However, in case an     operation such as vmsplice() required the kernel to take an additional reference to a shared page, and a     copy-on-write occurs during this operation, the kernel might have accessed the wrong process's memory. For     some programs, this could lead to an information leak or data corruption. This issue was already fixed for     most architectures, but not on MIPS and System z. This update corrects that. CVE-2020-36322,     CVE-2021-28950 The syzbot tool found that the FUSE (filesystem-in-user-space) implementation did not     correctly handle a FUSE server returning invalid attributes for a file. A local user permitted to run a     FUSE server could use this to cause a denial of service (crash). The original fix for this introduced a     different potential denial of service (infinite loop in kernel space), which has also been fixed.
    CVE-2021-3640 Lin Ma discovered a race condiiton in the Bluetooth protocol implementation that can lead to     a use-after-free. A local user could exploit this to cause a denial of service (memory corruption or     crash) or possibly for privilege escalation. CVE-2021-3744, CVE-2021-3764 minihanshen reported bugs in the     ccp driver for AMD Cryptographic Coprocessors that could lead to a resource leak. On systems using this     driver, a local user could exploit this to cause a denial of service. CVE-2021-3752 Likang Luo of NSFOCUS     Security Team discovered a flaw in the Bluetooth L2CAP implementation that can lead to a user-after-free.
    A local user could exploit this to cause a denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2021-3760, CVE-2021-4202 Lin Ma discovered race conditions in the NCI (NFC     Controller Interface) driver, which could lead to a use-after-free. A local user could exploit this to     cause a denial of service (memory corruption or crash) or possibly for privilege escalation. This driver     is not enabled in Debian's official kernel configurations. CVE-2021-3772 A flaw was found in the SCTP     protocol implementation, which would allow a networked attacker to break an SCTP association. The attacker     would only need to know or guess the IP addresses and ports for the association. CVE-2021-4002 It was     discovered that hugetlbfs, the virtual filesystem used by applications to allocate huge pages in RAM, did     not flush the CPU's TLB in one case where it was necessary. In some circumstances a local user would be     able to read and write huge pages after they are freed and reallocated to a different process. This could     lead to privilege escalation, denial of service or information leaks. CVE-2021-4083 Jann Horn reported a     race condition in the local (Unix) sockets garbage collector, that can lead to use-after-free. A local     user could exploit this to cause a denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2021-4135 A flaw was found in the netdevsim driver which would lead to an     information leak. This driver is not enabled in Debian's official kernel configurations. CVE-2021-4155     Kirill Tkhai discovered a data leak in the way the XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for     a size increase of files with unaligned size. A local attacker can take advantage of this flaw to leak     data on the XFS filesystem. CVE-2021-4203 Jann Horn reported a race condition in the local (Unix) sockets     implementation that can lead to a use-after-free. A local user could exploit this to leak sensitive     information from the kernel. CVE-2021-20317 It was discovered that the timer queue structure could become     corrupt, leading to waiting tasks never being woken up. A local user with certain privileges could exploit     this to cause a denial of service (system hang). CVE-2021-20321 A race condition was discovered in the     overlayfs filesystem driver. A local user with access to an overlayfs mount and to its underlying upper     directory could exploit this for privilege escalation. CVE-2021-20322 An information leak was discovered     in the IPv4 implementation. A remote attacker could exploit this to quickly discover which UDP ports a     system is using, making it easier for them to carry out a DNS poisoning attack against that system.
    CVE-2021-22600 The syzbot tool found a flaw in the packet socket (AF_PACKET) implementation which could     lead to incorrectly freeing memory. A local user with CAP_NET_RAW capability (in any user namespace) could     exploit this for denial of service (memory corruption or crash) or possibly for privilege escalation.
    CVE-2021-28711, CVE-2021-28712, CVE-2021-28713 (XSA-391) Juergen Gross reported that malicious PV backends     can cause a denial of service to guests being serviced by those backends via high frequency events, even     if those backends are running in a less privileged environment. CVE-2021-28714, CVE-2021-28715 (XSA-392)     Juergen Gross discovered that Xen guests can force the Linux netback driver to hog large amounts of kernel     memory, resulting in denial of service. CVE-2021-38300 Piotr Krysiuk discovered a flaw in the classic BPF     (cBPF) JIT compiler for MIPS architectures. A local user could exploit this to excute arbitrary code in     the kernel. This issue is mitigated by setting sysctl net.core.bpf_jit_enable=0, which is the default. It     is *not* mitigated by disabling unprivileged use of eBPF. CVE-2021-39685 Szymon Heidrich discovered a     buffer overflow vulnerability in the USB gadget subsystem, resulting in information disclosure, denial of     service or privilege escalation. CVE-2021-39686 A race condition was discovered in the Android binder     driver, that could lead to incorrect security checks. On systems where the binder driver is loaded, a     local user could exploit this for privilege escalation. CVE-2021-39698 Linus Torvalds reported a flaw in     the file polling implementation, which could lead to a use-after-free. A local user could exploit this for     denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2021-39713 The     syzbot tool found a race condition in the network scheduling subsystem which could lead to a use-after-     free. A local user could exploit this for denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2021-41864 An integer overflow was discovered in the Extended BPF (eBPF)     subsystem. A local user could exploit this for denial of service (memory corruption or crash), or possibly     for privilege escalation. This can be mitigated by setting sysctl kernel.unprivileged_bpf_disabled=1,     which disables eBPF use by unprivileged users. CVE-2021-42739 A heap buffer overflow was discovered in the     firedtv driver for FireWire-connected DVB receivers. A local user with access to a firedtv device could     exploit this for denial of service (memory corruption or crash), or possibly for privilege escalation.
    CVE-2021-43389 The Active Defense Lab of Venustech discovered a flaw in the CMTP subsystem as used by     Bluetooth, which could lead to an out-of-bounds read and object type confusion. A local user with     CAP_NET_ADMIN capability in the initial user namespace could exploit this for denial of service (memory     corruption or crash), or possibly for privilege escalation. CVE-2021-43975 Brendan Dolan-Gavitt reported a     flaw in the hw_atl_utils_fw_rpc_wait() function in the aQuantia AQtion ethernet device driver which can     result in denial of service or the execution of arbitrary code. CVE-2021-43976 Zekun Shen and Brendan     Dolan-Gavitt discovered a flaw in the mwifiex_usb_recv() function of the Marvell WiFi-Ex USB Driver. An     attacker able to connect a crafted USB device can take advantage of this flaw to cause a denial of     service. CVE-2021-44733 A race condition was discovered in the Trusted Execution Environment (TEE)     subsystem for Arm processors, which could lead to a use-after-free. A local user permitted to access a TEE     device could exploit this for denial of service (memory corruption or crash) or possibly for privilege     escalation. CVE-2021-45095 It was discovered that the Phone Network protocol (PhoNet) driver has a     reference count leak in the pep_sock_accept() function. CVE-2021-45469 Wenqing Liu reported an out-of-     bounds memory access in the f2fs implementation if an inode has an invalid last xattr entry. An attacker     able to mount a specially crafted image can take advantage of this flaw for denial of service.
    CVE-2021-45480 A memory leak flaw was discovered in the __rds_conn_create() function in the RDS (Reliable     Datagram Sockets) protocol subsystem. CVE-2022-0001 (INTEL-SA-00598) Researchers at VUSec discovered that     the Branch History Buffer in Intel processors can be exploited to create information side channels with     speculative execution. This issue is similar to Spectre variant 2, but requires additional mitigations on     some processors. This can be exploited to obtain sensitive information from a different security context,     such as from user-space to the kernel, or from a KVM guest to the kernel. CVE-2022-0002 (INTEL-SA-00598)     This is a similar issue to CVE-2022-0001, but covers exploitation within a security context, such as from     JIT-compiled code in a sandbox to hosting code in the same process. This can be partly mitigated by     disabling eBPF for unprivileged users with the sysctl: kernel.unprivileged_bpf_disabled=2. This update     does that by default. CVE-2022-0322 Eiichi Tsukata discovered a flaw in the sctp_make_strreset_req()     function in the SCTP network protocol implementation which can result in denial of service. CVE-2022-0330     Sushma Venkatesh Reddy discovered a missing GPU TLB flush in the i915 driver, resulting in denial of     service or privilege escalation. CVE-2022-0435 Samuel Page and Eric Dumazet reported a stack overflow in     the networking module for the Transparent Inter-Process Communication (TIPC) protocol, resulting in denial     of service or potentially the execution of arbitrary code. CVE-2022-0487 A use-after-free was discovered     in the MOXART SD/MMC Host Controller support driver. This flaw does not impact the Debian binary packages     as CONFIG_MMC_MOXART is not set. CVE-2022-0492 Yiqi Sun and Kevin Wang reported that the cgroup-v1     subsystem does not properly restrict access to the release-agent feature. A local user can take advantage     of this flaw for privilege escalation and bypass of namespace isolation. CVE-2022-0617 butt3rflyh4ck     discovered a NULL pointer dereference in the UDF filesystem. A local user that can mount a specially     crafted UDF image can use this flaw to crash the system. CVE-2022-0644 Hao Sun reported a missing check     for file read permission in the finit_module() and kexec_file_load() system calls. The security impact of     this is unclear, since these system calls are usually only available to the root user. CVE-2022-22942 It     was discovered that wrong file file descriptor handling in the VMware Virtual GPU driver (vmwgfx) could     result in information leak or privilege escalation. CVE-2022-24448 Lyu Tao reported a flaw in the NFS     implementation in the Linux kernel when handling requests to open a directory on a regular file, which     could result in a information leak. CVE-2022-24959 A memory leak was discovered in the     yam_siocdevprivate() function of the YAM driver for AX.25, which could result in denial of service.
    CVE-2022-25258 Szymon Heidrich reported the USB Gadget subsystem lacks certain validation of interface OS     descriptor requests, resulting in memory corruption. CVE-2022-25375 Szymon Heidrich reported that the     RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command, resulting in information leak     from kernel memory. For the oldstable distribution (buster), these problems have been fixed in version     4.19.232-1. This update additionally includes many more bug fixes from stable updates 4.19.209-4.19.232     inclusive. We recommend that you upgrade your linux packages.

(CVE-2021-28713)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: The timeout could even never trigger if the guest manages to have only one free     slot in its RX queue ring page and the next package would require more than one free slot, which may be     the case when using GSO, XDP, or software hashing. (CVE-2021-28714)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715)

    A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

    A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    (CVE-2021-4083)

    A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size     increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS     filesystem otherwise not accessible to them. (CVE-2021-4155)

    A use-after-free flaw in the Linux kernel TEE (Trusted Execution Environment) subsystem was found in the     way user calls ioctl TEE_IOC_OPEN_SESSION or TEE_IOC_INVOKE. A local user could use this flaw to crash the     system or escalate their privileges on the system. If the Linux system non configured with the     CONFIG_PREEMPT option or CONFIG_CPU_SW_DOMAIN_PAN option enabled, then it is unlikely that a user can     trigger this issue. (CVE-2021-44733)
