CVE-2023-52583 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ceph: fix deadlock or deadcode of misusing dget()

The lock order is incorrect between denty and its parent we should always make sure that the parent get the lock first.

But since this deadcode is never used and the parent dir will always be set from the callers let’s just remove it.
