What is CVE-2025-68764?

A vulnerability in the Linux kernel related to NFS automounted filesystems allows certain flags such as 'ro', 'noexec', 'nodev', and 'sync' to be improperly inherited. When automounting a filesystem, it is critical for security that the user-defined superblock mount options are preserved. Failure to do so may expose systems to unauthorized access or execution of dangerous operations. This vulnerability underscores the importance of maintaining strict control over filesystem mount configurations to safeguard system integrity.
