   An update that fixes three vulnerabilities is now available.

Description:

   This update for the Linux Kernel 5.3.18-59_27 fixes several issues.

   The following security issues were fixed:

   - CVE-2022-0185: Incorrect param length parsing in legacy_parse_param
     which could have led to a local privilege escalation (bsc#1194517).
   - CVE-2021-4028: Fixed use-after-free in RDMA listen() that could lead to
     DoS or privilege escalation by a local attacker (bsc#1193167).
   - CVE-2021-42739: The firewire subsystem had a buffer overflow related to
     drivers/media/firewire/firedtv-avc.c and
     drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled
     bounds checking (bsc#1184673).
