Overview

CVE-2026-97576 is a high-severity vulnerability. It was published on September 25, 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: v4l2-ctrls: validate HEVC tile counts

The stateless HEVC decoders read num_tile_columns_minus1 + 1 entries from

column_width_minus1[] and num_tile_rows_minus1 + 1 from row_height_minus1[]

and use them as tile-loop bounds, but std_validate_compound() does not

bound these u8 counts. Reject a V4L2_CTRL_TYPE_HEVC_PPS with tiling

enabled whose tile counts exceed the uAPI array capacity, mirroring the

existing compound-control range checks.

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.
