CVE-2026-21379

CVE-2026-21379 describes a memory corruption (buffer over-read) issue in Windows Compute caused by allocating memory with sizes that exceed the maximum allowed value. The CVSS 3.1 metrics indicate a high impact on confidentiality, integrity, and availability (C:H, I:H, A:H) with a local attack ve...

CVE-2026-55646

CVE-2026-55646 (vLLM) affects vLLM versions 0.22.0–0.23.0. The routes /v1/audio/transcriptions and /v1/audio/translations call request.file.read() to fully materialize an uploaded audio file before enforcing the documented size limit (default 25 MB). This can cause the server to allocate memory p...
