Descriptions
In the Linux kernel, the following vulnerability has been resolved:
libfs: fix get_stashed_dentry()
get_stashed_dentry() tries to optimistically retrieve a stashed dentry
from a provided location. It needs to ensure to hold rcu lock before it
dereference the stashed location to prevent UAF issues. Use
rcu_dereference() instead of READ_ONCE() it's effectively equivalent
with some lockdep bells and whistles and it communicates clearly that
this expects rcu protection.
