     security bugfixes.
  The following security bugs were fixed:

  - CVE-2022-2639: Fixed integer underflow that could lead to out-of-bounds
       write in reserve_sfa_size() (bsc#1202154).

  - CVE-2020-36516: Fixed TCP session data injection vulnerability via the
       mixed IPID assignment method (bnc#1196616).

  - CVE-2022-36946: Fixed an incorrect packet truncation operation which
       could lead to denial of service (bnc#1201940).

  - CVE-2022-29581: Fixed improper update of Reference Count in net/sched
       that could cause root privilege escalation (bnc#1199665).

  - CVE-2022-20166: Fixed several possible memory safety issues due to
       unsafe operations (bsc#1200598).

  - CVE-2020-36558: Fixed a race condition involving VT_RESIZEX which could
       lead to a NULL pointer dereference and general protection fault
       (bnc#1200910).

  - CVE-2020-36557: Fixed a race condition between the VT_DISALLOCATE ioctl
       and closing/opening of TTYs could lead to a use-after-free (bnc#1201429).

  - CVE-2022-21505: Fixed kexec lockdown bypass with IMA policy
       (bsc#1201458).

  - CVE-2021-33656: Fixed memory out of bounds write related to ioctl cmd
       PIO_FONT (bnc#1201636).

  - CVE-2021-33655: Fixed out of bounds write with ioctl FBIOPUT_VSCREENINFO
       (bnc#1201635).

  - CVE-2022-1462: Fixed an out-of-bounds read flaw in the TTY subsystem
       (bnc#1198829).

  - CVE-2022-1116: Fixed a integer overflow vulnerability in io_uring which
       allowed a local attacker to cause memory corruption and escalate
       privileges to root (bnc#1199647).

  - CVE-2022-2318: Fixed a use-after-free vulnerability in the timer handler
       in Rose subsystem that allowed unprivileged attackers to crash the
       system (bsc#1201251).

  - CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742: Fixed
       multiple potential data leaks with Block and Network devices when using
       untrusted backends (bsc#1200762).
  The following non-security bugs were fixed:

  - Fix bsc#1201644, bsc#1201664, bsc#1201672, bsc#1201673, bsc#1201676 All
       are reports of the same problem - the IBRS_* regs push/popping was wrong
       but it needs 1b331eeea7b8 ('x86/entry: Remove skip_r11rcx') too.

  - ACPI: APEI: Better fix to avoid spamming the console with old error logs
       (git-fixes).

  - ACPI: CPPC: Do not prevent CPPC from working in the future (git-fixes).

  - ACPI: video: Shortening quirk list by identifying Clevo by board_name
