Description Carlos López 2022-09-21 13:55:50 UTC

CVE-2022-41222

mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale
TLB because an rmap lock is not held during a PUD move.

Comment 1 Carlos López 2022-09-21 14:11:07 UTC

The fix [0] references two commits [1] [2]:
- We have [0] in SLE15-SP4, stable and master.
- We have [1] in SLE15-SP4, stable and master as well.
- We have [2] cve/linux-5.3, as well as in SLE15-SP4, stable and master.

So this affects only cve/linux-5.3, since it includes the original conditional logic for take_rmap_locks().
