CVE-2023-53748

Estado: AplazadaAlta (7.1)—

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

media: mediatek: vcodec: Fix potential array out-of-bounds in decoder queue_setup

variable *nplanes is provided by user via system call argument. The possible value of q_data->fmt->num_planes is 1-3, while the value of *nplanes can be 1-8. The array access by index i can cause array out-of-bounds.

Fix this bug by checking *nplanes against the array size.

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 sin UI requiere privilegios locales (PR:L), indicando escalada. El desbordamiento de búfer permite DoS o lectura de memoria kernel; acceso local elevado típico de T1068.

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.
