CVE-2026-24263

Firmware code execution via NULL pointer dereference

Published Aug 25, 2026 · Updated Aug 26, 2026

NULL pointer dereference in NVIDIA DGX Spark UEFI 1.110.12 and earlier allows local users to execute code and interrupt service. NVIDIA identifies the locus only as system firmware and has not disclosed which pointer is left null or what firmware input reaches the dereference. Administrative local access and no user interaction are required; successful exploitation can cross the firmware boundary to alter or disclose data, execute code, or interrupt service.
