Lmcache - Lmcache - CRITICAL - CVE-2026-105192. The LMCache distributed mode introduces a vulnerability where an unauthenticated ZeroMQ ROUTER allows worker processes to register and share key-value cache blocks. This may lead to code execution as the user running the LMCache process, potentially with elevated privileges if running as root. It involves a msgpack extension that is improperly deserialized using pickle, allowing malicious actors to send specially crafted messages to exploit this flaw.
