CVE-2026-43222

Estado: AnalizadaAlta (7.8)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:L/PR:L sin UI permite escalada local. Buffer overflow en kernel podría ejecutar código privilegiado o causar DoS; kernel verisilicon AV1 con escritura fuera de límites.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
