    session (bnc#1196616).
  • CVE-2021-4203: Fixed use-after-free read flaw that was found in
    sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and
    SO_PEERGROUPS race with listen() (bnc#1194535).
  • CVE-2022-1012: Fixed a memory leak problem that was found in the TCP
    source port generation algorithm in net/ipv4/tcp.c (bnc#1199482).

    the message handling could be confused and incorrectly matches the
    message (bnc#1202097).
