Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A vulnerability was found in vLLM up to 0.19.0. The affected element is the function has_mamba_layers of
 the file vllm/v1/kv_cache_interface.py of the component KV Block Handler. Performing a manipulation
 results in uninitialized resource. It is possible to initiate the attack remotely. The attack is
 considered to have high complexity. The exploitability is described as difficult. The exploit has been
 made public and could be used. The existence of this vulnerability is still disputed at present. The
 proposed patch did not fix the issue. A 3rd party explains: "The divergence could be explained by a benign
 and expected vLLM behavior where vLLM server could group concurrent requests together resulting in
 different input shapes based on varying request arrival time. The differences in grouped input shapes
 could call different kernels with could produce difference results due to rounding and differences in
 order of operations. There is an environment variable VLLM_BATCH_INVARIANT=1 for users that desire to have
 deterministic output with temperature 0.0." (CVE-2026-7141)

Solution

Update the vllm library and its related packages to version 0.19.1 or later.
