Description OSIDB Bzimport 2025-03-06 17:02:06 UTC 
In the Linux kernel, the following vulnerability has been resolved:

landlock: Handle weird files

A corrupted filesystem (e.g. bcachefs) might return weird files.
Instead of throwing a warning and allowing access to such file, treat
them as regular files.
