Description OSIDB Bzimport 2026-08-15 06:19:07 UTC 
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.
