An update that fixes two vulnerabilities is now available.

Description:

This update for the Linux Kernel 4.12.14-197_108 fixes several issues.
The following security issues were fixed:

  o CVE-2022-1016: Fixed a vulnerability in the nf_tables component of the
    netfilter subsystem. This vulnerability gives an attacker a powerful
    primitive that can be used to both read from and write to relative stack
    data, which can lead to arbitrary code execution. (bsc#1197335)
  o CVE-2022-1011: Fixed an use-after-free vulnerability which could allow a
    local attacker to retireve (partial) /etc/shadow hashes or any other data
    from filesystem when he can mount a FUSE filesystems. (bsc#1197344)
