CVE-2026-90554: vLLM versions >=0.10.2 and <0.28.0 do not apply any audio decode-size or duration limit when extracting audio

Q: How urgent is CVE-2026-90554?

Priority 24/100. No elevated risk signals yet.

Routine

MEDIUM 6.2UPGRADE

CVE-2026-90554 is a medium-severity flaw (CVSS 6.2) affecting vllm. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

vLLM versions >=0.10.2 and <0.28.0 do not apply any audio decode-size or duration limit when extracting audio from video input for NanoNemotronVL models. In nano_nemotron_vl.py, _extract_audio_from_videos calls load_audio_pyav(BytesIO(video_bytes)) without the max_duration_s or max_decode_bytes parameters, so neither VLLM_MAX_AUDIO_DECODE_DURATION_S nor VLLM_MAX_AUDIO_DECODE_BYTES is enforced (unlike the direct audio upload path in AudioMediaIO).

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

vllm vllm UPGRADE

Affected: >= 0.10.2 and < 0.28.0

Fixed in: 0.28.0

Safe to downgrade to: a release before 0.10.2

1. Check installed version

apt-cache policy vllm || rpm -q vllm || vllm --version

2. UPGRADE to 0.28.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade vllm

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade vllm

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 0.10.2 (Debian / Ubuntu)

apt-cache madison vllm sudo apt install vllm=<VERSION_BEFORE_0.10.2> sudo apt-mark hold vllm

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list vllm sudo dnf downgrade vllm-<VERSION_BEFORE_0.10.2> sudo dnf versionlock add vllm

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
