In the Linux kernel, the following vulnerability has been resolved:ima: Fix use-after-free on a dentry's dname.name->d_name.name can change on rename and the earlier value can be freed;there are conditions sufficient to stabilize it (->d_lock on dentry,->d_lock on its parent, ->i_rwsem exclusive on the parent's inode,rename_lock), but none of those are met at any of the sites. Take a stablesnapshot of the name instead.
