Overview

CVE-2026-68108 is a high-severity vulnerability. It was published on August 10, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, 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/amdgpu/vce: fix integer overflow in image size

Fix a security vulnerability where malicious VCE command streams

with oversized dimensions (e.g. 65536×65536) cause 32-bit integer

overflow, wrapping the calculated buffer size to 0. This bypasses

validation and allows GPU firmware to perform out-of-bound memory

access.

The fix uses 64-bit arithmetic to detect overflow and rejects

invalid dimensions before they reach the hardware.

V2: remove redundant check

V3: modify max height value

V4: remove size64

(cherry picked from commit cbe408dba581755ad1279a487ec786d8927d778d)

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.

How can CyberStrike help with CVE-2026-68108?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-68108 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
