Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An ABBA deadlock occurs in the NTFS driver due to conflicting lock acquisition orders between extent lock and mrec lock. The issue manifests through two competing paths: the inode writeback path, where ntfs write inode() acquires extent lock then mrec lock, and the MFT folio writeback path, where ntfs may write mft record() may hold an mrec lock and attempt to acquire an extent lock. An ABBA deadlock is a synchronization error where two different threads block each other by each acquiring one resource and waiting for the other to release the second resource.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
