PYSEC-2026-3935 vLLM: Cross-User Data Leak Vulnerability

Summary An integer overflow in the actandmulkernel kernel can cause the output of one user request to be incorporated into the response of another request within the same inference batch. Under certain conditions, the last request in a batch can receive a partial or complete copy of the first...

SUSE CVE-2026-73558

vLLM is an inference and serving engine for large language models. Prior to 0.27.0, an integer overflow in blockIdx.x 2 d in activationkernels.cu can cause actandmulkernel to consume another batched user's input, allowing a request processed in the same inference batch to receive a partial or...

CVE-2026-73558

A flaw was found in vLLM, an inference and serving engine for large language models. An integer overflow vulnerability in the actandmulkernel kernel allows a remote attacker to cause cross-user data leakage. By crafting specific requests processed in the same inference batch, an attacker can obta...

Integer Overflow or Wraparound

Overview vllm is an A high-throughput and memory-efficient inference and serving engine for LLMs Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to an integer overflow in the actandmulkernel in activationkernels.cu. An attacker can access another user's...
