CVE-2026-94626
Last modified
CVE-2026-94626 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. vLLM through 0.29.0 fails to validate the tp_size parameter in kv_transfer_params on OpenAI-compatible completion endpoints, allowing attackers to allocate unbounded memory. Attackers can supply arbitrary tp_size values in prefill/decode disaggregated deployments to exhaust memory and trigger kernel OOM-kill of the decode worker process.. EPSS estimates a 0.45% chance of exploitation in the next 30 days.
