Local service interruption via integer truncation
Published Dec 30, 2022 · Updated Apr 10, 2025
Integer truncation in the kernel-mode layer of NVIDIA vGPU Software 14.2 and earlier allows local users to interrupt service. The handler narrows an integer before a bounds-sensitive memory read, allowing the truncated value to produce an out-of-bounds read. Low-privilege local access is required; NVIDIA has not disclosed whether the resulting interruption is a crash, hang, or another failure mode.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=All versions prior to and including 14.2, 13.4, and 11.9, and all versions prior to the November 2022 release
