Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: call _ntfs_bad_inode() when failing to rename It is safe to call _ntfs_bad_inode on live inodes since: commit 519b078998ce ("fs/ntfs3: Exclude call make_bad_inode for live nodes.") The WARN_ON was added when it wasn't safe by: commit d99208b91933 ("fs/ntfs3: cancle set bad inode after removing name fails") Replace the WARN_ON with a call to _ntfs_bad_inode() to prevent further operations on the inconsistent inode.
