  * CVE-2023-4004: Fixed improper element removal netfilter nft_set_pipapo
    (bsc#1214812).
  * CVE-2023-3390: Fixed an use-after-free vulnerability in the netfilter
    subsystem in net/netfilter/nf_tables_api.c that could allow a local attacker
    with user access to cause a privilege escalation issue (bsc#1212934).
