Security readout for executives and security teams

This is an old local-user issue in openCryptoki 2.4.1. A user already on the system could abuse insecure lock-file handling under /var/lock to make arbitrary files world-writable. That could weaken system integrity, but the sources do not show remote exploitation, CVSS scoring, or CISA KEV listing. Exposure is likely limited to hosts running openCryptoki 2.4.1, especially multi-user Linux systems or systems exposing local shell access. Internet-only exposure is not supported by the provided sources. Treat this as a targeted hardening item unless affected hosts are multi-user, shared, or security-sensitive. Prioritize faster where local users are untrusted or where file permission tampering could affect privileged services. Mitigation focus: Identify and retire openCryptoki 2.4.1 installations.; Apply a vendor-supported fixed package or release guidance.; Review vendor notes around openCryptoki 2.4.2 and the referenced commit..
