CVE-2025-68369
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.
