CVE-2022-50182

Estado: ModificadaAlta (7.1)—

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

media: imx-jpeg: Align upwards buffer size

The hardware can support any image size WxH, with arbitrary W (image width) and H (image height) dimensions.

Align upwards buffer size for both encoder and decoder. and leave the picture resolution unchanged.

For decoder, the risk of memory out of bounds can be avoided. For both encoder and decoder, the driver will lift the limitation of resolution alignment.

For example, the decoder can support jpeg whose resolution is 227x149 the encoder can support nv12 1080P, won't change it to 1920x1072.

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 indica escalada local. CWE-125 (out-of-bounds read) permite DoS por corrupción de memoria del kernel y lectura de datos sensibles.

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.
