AMD, Arm, and Nvidia Release Security Advisories for Product Vulnerabilities

Chipmakers Address Security Flaws

Major chip manufacturers AMD, Arm, and Nvidia have released security advisories to inform customers about recently discovered vulnerabilities in their product lines. These advisories detail specific flaws and the corresponding patches or mitigation strategies.

AMD's Linux GPU Driver Vulnerability

AMD announced fixes for CVE-2026-43603, a NULL pointer dereference flaw found in its Linux GPU kernel driver. This vulnerability could lead to system crashes and denial-of-service (DoS) conditions. The issue occurs when a graphics memory management interface performs a 'clear' operation under certain compute-processing conditions, causing the driver to fail validation of an internal data reference.

Patches for EPYC Athlon, Ryzen, Radeon, and Instinct processors were released in July, with fixes for EPYC Embedded and Ryzen Embedded processors scheduled for October.

Arm Mali GPU Vulnerabilities

Arm published an advisory covering nine vulnerabilities in its Mali GPUs. These flaws could allow access to already freed memory, sensitive kernel information, or lead to denial-of-service conditions. Fixes have been released for the Valhall GPU and Arm 5th Gen GPU Architecture kernel and userspace drivers. The Bifrost GPU kernel and userspace drivers are also affected by these vulnerabilities.

Nvidia Triton Inference Server Update

Nvidia released a software update for its Triton Inference Server for Linux to resolve two high-severity security defects. One defect could result in a DoS condition, while the second could lead to information disclosure, data tampering, and DoS conditions.
