Overview

CVE-2026-68228 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:

media: chips-media: wave5: Move src_buf Removal to finish_encode

During encoder processing, there is a case where the IRQ response could

return the buffer back to userspace via v4l2_m2m_buf_done call. In this

time, userspace could queue up this same buffer before start_encode removes

the index from the ready queue. This would then lead to a case where the

buffer in the ready queue could be a self loop due to the

WRITE_ONCE(prev->next, new) call in __list_add.

When __list_del is finally called, the loop is already made so nothing

points back to ready queue list head and pointers are poisoned.

A buffer should not be marked as DONE before the buffer is removed from

m2m ready queue. Move removal entirely to finish_encode.

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-2026-68228?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-68228 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.
