Local privilege escalation via kernel integer overflow
Published Jan 28, 2026 · Updated Jan 28, 2026
Integer overflow in nvlddmkm.sys in NVIDIA GPU Display Driver for Windows allows local users to execute code with elevated privileges. NVIDIA identifies the kernel-mode driver as the locus but has not disclosed the attacker-controlled input or arithmetic operation that overflows. A local low-privilege account is required; exploitation can also tamper with or disclose data or interrupt the system.
