Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
GHSA-8wr5-jm2h-8r4f: vLLM versions >=0.17.1 and <0.24.0 are affected. A remote client that can send normal public gRPC Generate and Abort requests with overlapping speculative-decoding workloads can make an out-of-vocabulary recovered token reach the drafting path and crash the shared engine worker with a GPU device-side assert, causing a denial of service for other clients. Upgrade to vLLM 0.24.0, which contains the fix.
