CVE-2026-34194 (GCVE-0-2026-34194)

Vulnerability from cvelistv5 – Published: 2026-06-08 14:58 – Updated: 2026-06-08 18:55

Title

GPU DDK - UAF read and/or write to arbitrary physical pages in DevmemIntChangeSparse due to incorrect calculation of the virtual index count

Summary

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of a mapping state maintained for a sparse memory allocation. The product accidentally refers to the wrong memory due to the semantics of how math operations are implicitly scaled across buffers of different sizes.

Severity

7.1 (High)

GHSA-4FP7-72XG-C4HC

Vulnerability from github – Published: 2026-06-08 18:31 – Updated: 2026-06-08 21:31

Details

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of a mapping state maintained for a sparse memory allocation.

The product accidentally refers to the wrong memory due to the semantics of how math operations are implicitly scaled across buffers of different sizes.

Severity

7.1 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
