In the Linux kernel, the following vulnerability has been resolved: ntfs3: init run lock for extend inode After setting the inode mode of $Extend to a regular file, executing the truncate system call will enter the do_truncate() routine, causing the run_lock uninitialized error reported by syzbot. Prior to patch 4e8011ffec79, if the inode mode of $Extend was not set to a regular file, the do_truncate() routine would not be entered. Add the run_lock initialization when loading $Extend. syzbot reported: INFO: trying to register non-static key.
