CVE-2025-23299

Code execution via management-interface out-of-bounds write

Published Oct 22, 2025 · Updated Oct 22, 2025

Out-of-bounds write in NVIDIA BlueField and ConnectX management firmware allows local users with high privileges to execute arbitrary code. NVIDIA identifies the management interface as the affected locus but has not disclosed the command, buffer, or missing bounds check involved. Exploitation requires local high-privilege access and can compromise the firmware execution context's confidentiality, integrity, and availability.
