CVE-2026-47566: NVIDIA GPU Display Driver for Linux memory leak in kernel mode layer

CVE-2026-47566 · Severity: medium · CVSS 5.5 · Published 2026-09-30

NVIDIA's GPU display driver for Linux contains a memory leak vulnerability in its kernel-mode component that unprivileged users can trigger through error paths. An attacker could repeatedly exploit this to exhaust kernel memory, causing system crashes or service denial. This affects systems running NVIDIA GPUs with vulnerable driver versions on Linux.

Technologies: Nvidia GPU Display Driver for Linux. Vendors: Nvidia.

Technical details

The vulnerability is a memory leak in the kernel mode layer of the NVIDIA GPU display driver triggered by unprivileged users in error handling code paths. Exploitation requires local access to the affected system; repeated triggering of error conditions allows exhaustion of kernel memory leading to denial of service. A fix is expected from NVIDIA through driver updates.
