Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A flaw exists in the Linux kernel related to the NTFS3 file system. Specifically, an uninitialized run lock error can occur when handling the $Extend inode after setting its mode to a regular file and then executing a truncate system call. This issue arises because the run lock is not initialized when loading $Extend. The problem was reported by syzbot and addressed by initializing the run lock during the loading of $Extend.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
