Chipmaker Patch Tuesday: Nvidia, AMD, Arm Issue Security Advisories
Chipmakers AMD, Arm, and Nvidia released security patches this week to address vulnerabilities in their hardware and software. These flaws could lead to denial-of-service attacks, data breaches, and system crashes, highlighting the ongoing need for timely updates and proactive security measures within the tech industry.
Several major chipmakers, including AMD, Arm, and Nvidia, released security advisories on Tuesday addressing critical vulnerabilities in their products. These updates are part of the regular ‘Patch Tuesday’ process, a common practice among technology companies to address security weaknesses.
AMD announced fixes for CVE-2026-43603, a NULL pointer dereference flaw in its Linux GPU kernel driver. According to AMD, this vulnerability could result in system crashes and a denial-of-service (DoS) condition. The company acknowledged the report from SecMate researchers Maxime Rossi Bellom and Ramtine Tofighi Shirazi, who identified the issue.
Arm published an advisory covering nine vulnerabilities in its Mali GPUs. These flaws could allow unauthorized access to already freed memory, expose sensitive kernel information, or trigger a DoS condition. The fixes address vulnerabilities in the Valhall GPU and Arm 5th Gen GPU Architecture kernel and userspace drivers, as well as the Bifrost GPU kernel and userspace drivers.
Nvidia released a software update for the Triton Inference Server for Linux, addressing two high-severity security defects. One vulnerability could lead to a DoS condition, while the second could result in information disclosure, data tampering, and further DoS conditions. At the time of publication, Intel had not yet released any new security advisories for this Patch Tuesday.
