Overview

CVE-2026-68229 is a high-severity vulnerability. It was published on August 10, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, 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: cedrus: skip invalid H.264 reference list entries

Cedrus consumes H.264 ref_pic_list0/ref_pic_list1 entries from the

stateless slice control and later uses their indices to look up

decode->dpb[] in _cedrus_write_ref_list().

Rejecting such controls in cedrus_try_ctrl() would break existing

userspace, since stateless H.264 reference lists may legitimately carry

out-of-range indices for missing references. Instead, guard the actual

DPB lookup in Cedrus and skip entries whose indices do not fit the fixed

V4L2_H264_NUM_DPB_ENTRIES array.

This keeps the fix local to the driver use site and avoids out-of-bounds

reads from malformed or unsupported reference list entries.

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.
