Overview

CVE-2025-38080 is a high-severity vulnerability. It was published on June 18, 2025 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: Increase block_sequence array size

[Why]

It's possible to generate more than 50 steps in hwss_build_fast_sequence,

for example with a 6-pipe asic where all pipes are in one MPC chain. This

overflows the block_sequence buffer and corrupts block_sequence_steps,

causing a crash.

[How]

Expand block_sequence to 100 items. A naive upper bound on the possible

number of steps for a 6-pipe asic, ignoring the potential for steps to be

mutually exclusive, is 91 with current code, therefore 100 is sufficient.

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-2025-38080?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2025-38080 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.
