CVE-2012-4454
openCryptoki before 2.4.1, when using spinlocks, allows local users to create or set world-writable permissions on arbitrary files via a symlink attack on the (1) .pkapi_xpk or (2) .pkcs11spinloc file in /tmp.
Does this matter?
Lower severity and a low EPSS score (1.13%). Track it; it rarely justifies an emergency change on its own.
