How to fix?

There is no fixed version for RHEL:7 clevis-udisks2.

NVD Description

Note: Versions mentioned in the description apply only to the upstream clevis-udisks2 package and not the clevis-udisks2 package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
