CHIPMAKER Patch Tuesday brought a trio of security advisories from AMD, Arm and Nvidia, detailing fixes for recently disclosed flaws across their graphics and compute products. AMD’s advisory addresses CVE-2026-43603, a NULL pointer dereference in the Linux GPU kernel driver that could crash systems or trigger a denial-of-service.
AMD notes the issue arises when an application uses a graphics memory management interface to perform a “clear” operation under certain compute conditions, with the driver failing to validate an internal data reference. Patches have already been released for EPYC Athlon, Ryzen, Radeon and Instinct processors, and AMD plans updates for EPYC Embedded and Ryzen Embedded in October. The vulnerability was reported by researchers from SecMate.
Arm’s advisory covers nine vulnerabilities in Mali GPUs that could allow access to freed memory or sensitive kernel information, or cause DoS. The fixes are now available for the Valhall GPU and Arm 5th Gen GPU Architecture kernel and userspace drivers, with Bifrost GPU kernel and userspace drivers also implicated.
Nvidia disclosed a software update for the Triton Inference Server on Linux addressing two high-severity defects: one could cause a DoS, while the other could enable information disclosure, data tampering and DoS. At press time there were no new Intel advisories cited alongside these updates. The article notes no additional patches from Intel since the prior Patch Tuesday.
