In the Linux kernel, the following vulnerability has been resolved:
ksmbd: call ksmbd_vfs_kern_path_end_removing() on some error paths
There are two places where ksmbd_vfs_kern_path_end_removing() needs to be
called in order to balance what the corresponding successful call to
ksmbd_vfs_kern_path_start_removing() has done, i.e. drop inode locks and
put the taken references. Otherwise there might be potential deadlocks
and unbalanced locks which are caught like:
BUG: workqueue leaked lock or atomic: kworker/5:21/0x00000000/7596
last function: handle_ksmbd_work
2 locks held by kworker/5:21/7596:
