Security update for the Linux Kernel (Live Patch 11 for SLE 15 SP4)

This update for the Linux Kernel 5.14.21-150400_24_60 fixes several issues.

The following security issues were fixed:

  • CVE-2023-6531: Fixed a use-after-free flaw due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic()on the socket that the SKB is queued on (bsc#1218487).
  • CVE-2023-46813: Fixed a local privilege escalation with user-space programs that have access to MMIO regions (bsc#1216898).
  • CVE-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race condition in bt_sock_recvmsg (bsc#1218610).

Описание

An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it.
