  * 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)
