## Description:

This update for the Linux Kernel 5.3.18-150300_59_133 fixes several issues.

The following security issues were fixed:

  * CVE-2023-3777: Fixed a use-after-free vulnerability in netfilter: nf_tables
    component can be exploited to achieve local privilege escalation.
    (bsc#1215097)
  * CVE-2023-4622: Fixed a use-after-free vulnerability in the Unix domain
    sockets component which could be exploited to achieve local privilege
    escalation (bsc#1215442).
  * CVE-2023-2163: Fixed an incorrect verifier pruning in BPF that could lead to
    unsafe code paths being incorrectly marked as safe, resulting in arbitrary
    read/write in kernel memory, lateral privilege escalation, and container
    escape. (bsc#1215519)
