CVE-2026-45201 (GCVE-0-2026-45201)

Vulnerability from cvelistv5 – Published: 2026-08-21 04:01 – Updated: 2026-08-27 17:49

Title

GPU DDK - Incorrect page size validation in PhysmemNewRamBackedPMR could lead to OOB read and/or write of arbitrary physical memory

Summary

Software installed and run as a non-privileged user may conduct improper GPU system calls to pass invalid log2 page size when allocating physical pages leading to OOB read and/or write due to improper validation of the said value. Such crafted log2 page size could lead to 4K pages being treated as higher order pages and allowing read and/or write access to the memory beyond 4K threshold.

Severity

7.8 (High)
