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

    CVE-2021-4159

        A flaw was found in the eBPF verifier which could lead to an         out-of-bounds read.  If unprivileged use of eBPF is enabled, this         could leak sensitive information.  This was already disabled by         default, which would fully mitigate the vulnerability.

    CVE-2021-33655

        A user with access to a framebuffer console device could cause a         memory out-of-bounds write via the FBIOPUT_VSCREENINFO ioctl.

    CVE-2021-33656

        A user with access to a framebuffer console device could cause a         memory out-of-bounds write via some font setting ioctls.  These         obsolete ioctls have been removed.

    CVE-2022-1462

         reported a race condition in the pty (pseudo-terminal)         subsystem that can lead to a slab out-of-bounds write.  A local         user could exploit this to cause a denial of service (crash or         memory corruption) or possibly for privilege escalation.

    CVE-2022-1679

        The syzbot tool found a race condition in the ath9k_htc driver         which can lead to a use-after-free.  This might be exploitable to         cause a denial service (crash or memory corruption) or possibly         for privilege escalation.

    CVE-2022-2153

        kangel reported a flaw in the KVM implementation for x86         processors which could lead to a null pointer dereference. A local         user permitted to access /dev/kvm could exploit this to cause a         denial of service (crash).

    CVE-2022-2588

        Zhenpeng Lin discovered a use-after-free flaw in the cls_route         filter implementation which may result in local privilege         escalation for a user with the CAP_NET_ADMIN capability in any         user or network namespace.

    CVE-2022-2663

        David Leadbeater reported flaws in the nf_conntrack_irc         connection-tracking protocol module.  When this module is enabled         on a firewall, an external user on the same IRC network as an         internal user could exploit its lax parsing to open arbitrary TCP         ports in the firewall, to reveal their public IP address, or to         block their IRC connection at the firewall.

    CVE-2022-3028

        Abhishek Shah reported a race condition in the AF_KEY subsystem,         which could lead to an out-of-bounds write or read.  A local user         could exploit this to cause a denial of service (crash or memory         corruption), to obtain sensitive information, or possibly for         privilege escalation.

    CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742

        Roger Pau Monne discovered that Xen block and network PV device         frontends don't zero out memory regions before sharing them with         the backend, which may result in information disclosure.
        Additionally it was discovered that the granularity of the grant         table doesn't permit sharing less than a 4k page, which may also         result in information disclosure.

    CVE-2022-26373

        It was discovered that on certain processors with Intel's Enhanced         Indirect Branch Restricted Speculation (eIBRS) capabilities there         are exceptions to the documented properties in some situations,         which may result in information disclosure.

        Intel's explanation of the issue can be found at         https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-     guidance/advisory-guidance/post-barrier-return-stack-buffer-predictions.html

    CVE-2022-33744

        Oleksandr Tyshchenko discovered that ARM Xen guests can cause a         denial of service to the Dom0 via paravirtual devices.

    CVE-2022-36879

        A flaw was discovered in xfrm_expand_policies in the xfrm         subsystem which can cause a reference count to be dropped twice.

    CVE-2022-36946

        Domingo Dirutigliano and Nicola Guerrera reported a memory         corruption flaw in the Netfilter subsystem which may result in         denial of service.

    CVE-2022-39188

        Jann Horn reported a race condition in the kernel's handling of         unmapping of certain memory ranges.  When a driver created a         memory mapping with the VM_PFNMAP flag, which many GPU drivers do,         the memory mapping could be removed and freed before it was         flushed from the CPU TLBs.  This could result in a page use-after-         free.  A local user with access to such a device could exploit         this to cause a denial of service (crash or memory corruption) or         possibly for privilege escalation.

    CVE-2022-39842

        An integer overflow was discovered in the pxa3xx-gcu video driver         which could lead to a heap out-of-bounds write.

        This driver is not enabled in Debian's official kernel         configurations.

    CVE-2022-40307

        A race condition was discovered in the EFI capsule-loader driver,         which could lead to use-after-free.  A local user permitted to         access this device (/dev/efi_capsule_loader) could exploit this to         cause a denial of service (crash or memory corruption) or possibly         for privilege escalation.  However, this device is normally only         accessible by the root user.

    For Debian 10 buster, these problems have been fixed in version     4.19.260-1.

    We recommend that you upgrade your linux packages.

    A-182388481References: Upstream kernel (CVE-2022-20166)

  - A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it     possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This     flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel     oops condition that results in a denial of service. (CVE-2022-2153)

  - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that     allow attackers to crash linux kernel without any privileges. (CVE-2022-2318)

  - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text     explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device     frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740).
    Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to     unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend     (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)

  - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions. (CVE-2022-29581)

  - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

  - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free. (CVE-2022-32250)

  - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are     used. This occurs because of use of Algorithm 4 ('Double-Hash Port Selection Algorithm') of RFC 6056.
    (CVE-2022-32296)

  - An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer     overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point     registers. (CVE-2022-32981)

  - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree     to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the     related lock held, resulting in a small race window, which can be used by unprivileged guests via PV     devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS)     of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory     pages. (CVE-2022-33744)

  - drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of     a concurrency use-after-free flaw after deallocating raw_cmd in the raw_cmd_ioctl function.
    (CVE-2022-33981)

  - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init     (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different     vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an     unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data     in net/netfilter/nf_tables_api.c. (CVE-2022-34918)
