An update that solves five vulnerabilities can now be installed.

Description:

This update for the Linux Kernel 5.3.18-59_19 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-2021-4154: Fixed option parsing with cgroups version 1 (bsc#1193842).
• 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-2020-3702: Fixed a bug which could be triggered with specifically timed and handcrafted traffic and cause internal errors in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure. (bsc#1191193)
• 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).
