Overview

CVE-2026-68236 is a high-severity vulnerability. It was published on August 10, 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/display: set new_stream to NULL after release

In dm_update_crtc_state(), the skip_modeset path releases new_stream

via dc_stream_release() but does not set the pointer to NULL.

If a later error (e.g., color management failure) triggers the fail

label, the error path calls dc_stream_release() again on the same

dangling pointer, causing a double release and potential use-after-free.

Fix this by setting new_stream to NULL after the initial release.

(cherry picked from commit 99f3af19073b3ddbfd96e789124cce12c4277b28)

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.
