Security update for the Linux Kernel (Live Patch 23 for SLE 15 SP3)

This update for the Linux Kernel 5.3.18-150300_59_90 fixes several issues.

The following security issues were fixed:

  • CVE-2022-39188: Fixed a race condition between unmap_mapping_range() and munmap() on VM_PFNMAP mappings leads to stale TLB entry (bsc#1203116).
  • CVE-2021-39698: Fixed a memory corruption due to a use after free that could lead to local escalation of privilege with no additional execution privileges needed (bsc#1196959).

Описание

An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.
