CVE-2026-97580 Linux CVE debrief
A Linux kernel vulnerability has been resolved, affecting the media: rkvdec component. The vulnerability is related to bounding HEVC tile loops and PPS id to the array capacity. This issue was addressed by using the bounded v4l2_hevc_pps_num_tile_columns() and v4l2_hevc_pps_num_tile_rows() helpers for the tile loops, and bailing out of assemble_hw_pps() before indexing priv_tbl->param_set[] with an out-of-range pic_parameter_set_id. Linux kernel maintainers, Linux distribution vendors, and users of Linux-based systems should assess and apply patches for CVE-2026-97580.

Technical summary
The Linux kernel vulnerability CVE-2026-97580 is related to the media: rkvdec component. The vulnerability has been resolved by bounding HEVC tile loops and PPS id to the array capacity. This issue was addressed by using the bounded v4l2_hevc_pps_num_tile_columns() and v4l2_hevc_pps_num_tile_rows() helpers for the tile loops, and bailing out of assemble_hw_pps() before indexing priv_tbl->param_set[] with an out-of-range pic_parameter_set_id. The vulnerability affects Linux kernel versions and has been addressed by the Linux kernel maintainers.
Defensive priority
Assess and apply patches for Linux kernel vulnerability CVE-2026-97580
Recommended defensive actions
- Assess Linux kernel versions for potential exposure
- Apply patches for Linux kernel vulnerability CVE-2026-97580
- Verify bounding of HEVC tile loops and PPS id to array capacity
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
