Overview

CVE-2026-68106 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/amdgpu: fix division by zero with invalid uvd dimensions

When width or height is less than 16, width_in_mb or height_in_mb

becomes 0, leading to fs_in_mb being 0. This causes a division by

zero when calculating num_dpb_buffer in H264 and H264 Perf decode

paths.

Add validation to reject frames with width < 16 or height < 16

before performing any calculations that depend on these values.

V2: Format change - move up all vaiable definitions.

V3: Use warn_once to avoid spam.

(cherry picked from commit 3e41d26c70b0a459d041cc19482a226c4b7423cb)

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.
