Short explanation
A missing authentication vulnerability in the clevis PKCS#11 pin allows local users to access sensitive data through AF_UNIX sockets.
Unauthorized local users can inject device and key pairs into the control socket or connect to the data socket to retrieve LUKS passphrases.
What should be done?
- Follow vendor security advisories
- Apply relevant updates
- Review process umask settings

Show the technical text from the sources
A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon creates AF_UNIX sockets without explicit permission restrictions or peer credential verification. Under a permissive process umask, any local user can connect to the control socket and inject arbitrary device/key pairs, or connect to the data socket to receive LUKS passphrases.
