Integer overflow in NVIDIA GPU Display Driver for Windows kernel-mode (nvlddmkm.sys)

IdentifiersCVE-2025-33218CWE-190· Integer Overflow or Wraparound

NVIDIA GPU Display Driver for Windows contains an integer overflow vulnerability in the kernel-mode layer component nvlddmkm.sys. An attacker can trigger an integer overflow in this kernel driver, which NVIDIA indicates may be exploitable to achieve code execution and/or escalation of privileges, and may also enable data tampering, denial of service, or information disclosure.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation may result in kernel-level code execution and/or privilege escalation on Windows systems running the vulnerable NVIDIA display driver. NVIDIA also notes potential outcomes including data tampering, denial of service, and information disclosure.

Mitigation

If you can’t patch tonight, do this now.

No specific mitigations were provided in the supplied content beyond applying NVIDIA’s driver updates. Where immediate patching is not possible, reduce exposure by limiting untrusted local code execution on affected hosts (since exploitation is described as requiring only low-level privileges).

Remediation

Patch, then assume compromise.

Update the NVIDIA GPU Display Driver for Windows to a patched release for the applicable branch. NVIDIA-recommended fixed versions (by branch) include 591.59 (R590), 582.16 (R580), 573.96 (R570), or 539.64 (R535).
