CVE-2026-109970 · Clevis: clevis: pkcs#11 token pin written to world-readable file

This page contains facts from public vulnerability sources. Check the original advisory before updating.

A flaw was found in the clevis PKCS#11 pin. The clevis-luks-pkcs11-askpin script writes the PKCS#11 token PIN in plaintext to a file without setting restrictive permissions. Under the default process umask, the file is world-readable. Additionally, the PIN file is not reliably cleaned up if the decryption script exits early, leaving the PIN accessible indefinitely.
