Published: May 6, 2026· Updated: May 8, 2026

7.8
CVSS v3.1
EPSS:0.02%probability of exploitation in 30 daysPercentile:4.9th

Official Description

In the Linux kernel, the following vulnerability has been resolved:

media: verisilicon: AV1: Fix tile info buffer size

Each tile info is composed of: row_sb, col_sb, start_pos

and end_pos (4 bytes each). So the total required memory

is AV1_MAX_TILES * 16 bytes.

Use the correct #define to allocate the buffer and avoid

writing tile info in non-allocated memory.

Technical Analysis

CVE-2026-43222 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
