       system without any privileges (bsc#1201251).

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

       (bsc#1201458).

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

       that could allow local privilege escalation (bnc#1200015).

  - CVE-2022-36946: Fixed incorrect packet truncation in nfqnl_mangle() that
       could lead to remote DoS (bnc#1201940).
  The following non-security bugs were fixed:

  - 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
