NVD Description

Note: Versions mentioned in the description apply only to the upstream dlm-kmp-rt package and not the dlm-kmp-rt package as distributed by SLES.

A race condition was discovered in get_old_root in fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (BUG) because of a lack of locking on an extent buffer before a cloning operation, aka CID-dbcc7d57bffc.
