Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A locking issue in the Linux kernel's f2fs file system has been resolved. The problem occurred because spin lock(&sbi->error lock) was called before spin lock init() was called, resulting in a lockdep warning at f2fs handle error(). To address this, the initialization of locks in f2fs fill super() has been moved to immediately after memory allocation, ensuring safe locking in error handling.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
