SCA: security update for lmcache (GHSA-w5f2-9q9c-ff4h)

critical Tenable Cloud Security Plugin ID 476084

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - LMCache multiprocess mode, also called distributed mode, opens an unauthenticated ZeroMQ ROUTER so worker
 processes can register and share KV cache blocks. Messages on that socket are msgpack. Extension code 1 is
 passed to DeviceIPCWrapper.Deserialize, which calls pickle.loads, while the server is still decoding
 request arguments and before the handler runs. A single unauthenticated ZMQ DEALER message to the
 transport port (default 5555) therefore executes code as the user the LMCache process runs as. Official
 container images run that process as root. The transport binds to localhost unless the operator sets a
 routable address with --host, which is how multi-node deployments let peers connect. (CVE-2026-105192)

Solution

Update the lmcache library and its related packages to version 0.5.6 or later.
