CVE-2023-53129

Published: May 6, 2025Last modified: May 6, 2025

Description

In the Linux kernel, the following vulnerability has been resolved: ext4: Fix deadlock during directory rename As lockdep properly warns, we should not be locking i_rwsem while having transactions started as the proper lock ordering used by all directory handling operations is i_rwsem -> transaction start. Fix the lock ordering by moving the locking of the directory earlier in ext4_rename().
