Information disclosure via excess physical-page mapping
Published Dec 30, 2022 · Updated Apr 11, 2025
Information disclosure in NVIDIA vGPU Software before the November 2022 release allows local users to read protected memory. The Linux kernel-mode layer handler invokes a helper that maps more physical pages than the caller requested, exposing memory outside the intended mapping. Local execution against an affected Linux guest driver or Virtual GPU Manager is required; the result is protected-memory disclosure and limited data tampering.

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
