Security update for the Linux Kernel (Live Patch 3 for SLE 15 SP4)

This update for the Linux Kernel 5.14.21-150400_24_21 fixes several issues.

The following security issues were fixed:

  • CVE-2022-4379: A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel. This flaw allowed an attacker to conduct a remote denial of service attack (bsc#1206373).
  • CVE-2022-3424: Fixed use-after-free in gru_set_context_option(), gru_fault() and gru_handle_user_call_os() that could lead to kernel panic (bsc#1204167).
  • CVE-2022-2602: Fixed a local privilege escalation vulnerability involving Unix socket Garbage Collection and io_uring (bsc#1205186).

Описание

A use-after-free flaw was found in the Linux kernel's SGI GRU driver in the way the first gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate their privileges on the system.
