Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The Linux kernel contained a potential deadlock situation within the f2fs filesystem. The deadlock involved a chain of locks held by kswapd and other processes during operations like inode eviction, truncation, and atomic write commits. The root cause was identified as a circular dependency between multiple locks (Lock A, Lock B, Lock C, and Lock D) acquired in different code paths. This could occur during filesystem reclaim, inode eviction, and I/O operations.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
