vLLM Remote Engine Crash Vulnerability in CVE-2026-114050

Sources read

Source agreement

0/2

Evidence confidence

%44

Short explanation

CVE-2026-114050 is a remote engine crash vulnerability affecting vLLM versions prior to 0.31.0. It occurs because a client-supplied multimodal uuid is used verbatim as a cache identity without consistency checks, leading to engine termination.

Why does it matter?

This vulnerability allows attackers to desynchronize processor caches, causing a fatal mismatch that kills the entire serving instance until it is manually restarted.

What should be done?

Follow vendor advisories
Upgrade vLLM to 0.31.0 or later

Show the technical text from the sources

vLLM before 0.31.0 uses a client-supplied multimodal uuid verbatim as cache identity with no consistency check on cache hits, allowing engine crashes. Unauthenticated attackers can desynchronize the P0/P1 processor caches to trigger a fatal token-placeholder mismatch, killing the entire serving instance until restarted.
