    Published: 25 Feb 2022Last Modified: 12 Aug 2026

    Summary: Local Denial of Service in fscrypt PAM module

    Details: The PAM module for fscrypt doesn't adequately validate fscrypt metadata files, allowing users to create malicious metadata files that prevent other users from logging in. A local user can cause a denial of service by creating a fscrypt metadata file that prevents other users from logging into the system. We recommend upgrading to version 0.3.3 or above
