   An update that fixes three vulnerabilities is now available.

Description:

   This update for the Linux Kernel 5.3.18-150300_59_49 fixes several issues.

   The following security issues were fixed:

   - 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)
   - CVE-2022-1055: Fixed a use-after-free in tc_new_tfilter that could allow
     a local attacker to gain privilege escalation. (bnc#1197705)
   - 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)
