What is CVE-2025-39734?

A vulnerability in the Linux kernel relates to an earlier change in the file system's inode locking mechanism, which was reverted to address a deadlock issue reported during testing. The initial fix inadvertently removed conditional lock acquisition, leading to increase instability. The reversion corrects these issues, restoring the locking mechanism's efficiency and preventing potential deadlocks during file operations, thus enhancing overall system robustness.
