Hi,

The following vulnerability was published for clevis.

CVE-2026-109976[0]:
| A flaw was found in the clevis PKCS#11 pin. The clevis-
| pkcs11-afunix-socket-unlock daemon crashes when an AF_UNIX client
| connects to the data socket without a bound address, due to an
| integer underflow in the getpeername result handling. This causes a
| denial of service, preventing LUKS disk decryption from completing
| during boot.
