Description OSIDB Bzimport 2026-01-05 10:02:46 UTC 
In the Linux kernel, the following vulnerability has been resolved:

NFS: Automounted filesystems should inherit ro,noexec,nodev,sync flags

When a filesystem is being automounted, it needs to preserve the
user-set superblock mount options, such as the "ro" flag.
