Overview

CVE-2026-97578 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: verisilicon: rockchip: guard VPU981 AV1 divisor and tile buffer

rockchip_vpu981_av1_dec_set_tile_info() divides context_update_tile_id by

tile_info->tile_cols and writes one descriptor per tile into the tile_info

DMA buffer, which holds AV1_MAX_TILES entries; tile_cols and tile_rows

come from the bitstream. Guard the division against a zero tile_cols by

initialising the context-update values to zero and computing them only

when tile_cols is non-zero, and stop the descriptor writes once the

tile_info buffer is full. The tile geometry written to the hardware

registers is left unmodified; the per-dimension and total tile bounds are

enforced by the control validation.

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-2026-97578?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-97578 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.
