Vulnerability from cvelistv5 – Published: 2026-08-07 01:53 – Updated: 2026-08-07 17:54

Title

GPU DDK - Out of bounds memory access and kernel NULL pointer dereference in DmaTransfer when pui64Address is a pointer to device memory

Summary

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger OOB access and kernel null pointer dereference in an error path. Null pointer dereference occurs in an error path of a function running in kernel thread of execution leading to kernel exceptions, platform instability and denial of service.

Severity

5.5 (Medium)

GHSA-6G52-RC6P-5579

Vulnerability from github – Published: 2026-08-07 03:30 – Updated: 2026-08-07 18:31

Details

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger OOB access and kernel null pointer dereference in an error path.

Null pointer dereference occurs in an error path of a function running in kernel thread of execution leading to kernel exceptions, platform instability and denial of service.

Severity

5.5 (Medium)
