Nvidia, AMD, and Arm Issue Security Advisories Amid Patch Tuesday

Chipmakers Nvidia, AMD, and Arm recently published security advisories to notify customers of vulnerabilities in their products.

AMD released patches for CVE-2026-43603, a NULL pointer dereference flaw in its Linux GPU kernel driver that could cause system crashes and denial-of-service (DoS) conditions.

The company credited Maxime Rossi Bellom and Ramtine Tofighi Shirazi from SecMate for reporting the security defect. AMD's advisory notes that when an application invokes a specific graphics memory management interface to perform a 'clear' operation under certain compute-processing conditions, the driver may fail to validate an internal data reference before use.

Nvidia announced a software update for the Triton Inference Server for Linux that resolves two high-severity security defects. One could lead to a DoS condition, while the other could result in information disclosure, data tampering, and DoS conditions.
