Short explanation
A vulnerability exists in the clevis PKCS#11 pin component where the clevis-luks-pkcs11-askpin script writes the PKCS#11 token PIN in plaintext to a file without setting restrictive permissions.
This vulnerability is important because it can allow unauthorized users to read sensitive PIN data, leading to confidentiality breaches.
What should be done?
- Follow vendor advisories
- Manually restrict file permissions
- Apply updates

Show the technical text from the sources
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.
