What to do
AI-suggested
No explicit patch links or vendor advisory are provided in the input data. Until a fix is applied, avoid operations that trigger mount moves or unmounts concurrently with do_move_mount() usage in sensitive environments.
Description
CVE-2025-37988 addresses race conditions in the Linux kernel's do_move_mount() function related to MNT_TREE_BENEATH handling. The issue arises from insufficient locking when handling mountpoints beneath a given path, which can lead to filesystem shutdown while references are still held. The fix involves improved locking and pinning of both dentry and mount objects to prevent races and ensure filesystem stability during mount moves.
