Detailsinfo

A vulnerability was found in Linux Kernel (unknown version). It has been classified as critical. Affected is the function ext4_rename of the component ext4. The manipulation with an unknown input leads to a deadlock vulnerability. CWE is classifying the issue as CWE-833. The product contains multiple threads or executable segments that are waiting for each other to release a necessary lock, resulting in deadlock. This is going to have an impact on availability. CVE summarizes:

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().
