Description OSIDB Bzimport 2025-12-24 12:03:22 UTC 
In the Linux kernel, the following vulnerability has been resolved:

SMB3: Add missing locks to protect deferred close file list

cifs_del_deferred_close function has a critical section which modifies
the deferred close file list. We must acquire deferred_lock before
calling cifs_del_deferred_close function.
