This affects the function hex_hash_to_int16 of the file lmcache/integration/vllm/utils.py of the component KV Cache Handler. Executing a manipulation can lead to use of weak hash. The attack needs to be launched locally. The attack requires a high level of complexity. It is indicated that the exploitability is difficult. The exploit has been published and may be used. The pull request to fix this issue awaits acceptance.\n\n## Affected packages\n\n- `lmcache <= 0.4.6`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":20,"depthScoreParts":{"impact":19.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
