Description OSIDB Bzimport 2026-08-15 06:25:18 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ntfs: validate index entries on reading

Validate index entries immediately after reading an index root or index
block from disk. This eliminates repeated checks in lookup and readdir,
and reduce the risk of missing checks in those paths.
