What is CVE-2025-21830?

A vulnerability exists in the Linux kernel's Landlock feature where corrupted filesystem structures, such as those in bcachefs, could be treated as regular files. This anomalous behavior bypasses necessary warnings and allows access to potentially unsafe files, posing a risk to system integrity. Proper mitigation strategies must be implemented to ensure that access to such corrupted files is handled appropriately.
