CVE-2026-68229 — media: cedrus: skip invalid H.264 reference list entries

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
