Overview

CVE-2026-74450 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/pm: fix pptable use-after-free

amdgpu_dpm_get_pp_table() returns a pointer to a driver-owned power table

after dropping adev->pm.mutex. The sysfs path then copies from that pointer.

A concurrent pp_table write can replace and free the allocation during the

copy, causing a use-after-free.

Change the DPM interface to copy into caller-provided storage while the mutex

is held. Keep the size-only query for attribute discovery without exposing

the driver-owned pointer.

(cherry picked from commit f6eed7acfd30099ef7baeb6ba45bb59daad80631)

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
