CVE-2024-57983

Estado: ModificadaAlta (7.8)—

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

mailbox: th1520: Fix memory corruption due to incorrect array size

The functions th1520_mbox_suspend_noirq and th1520_mbox_resume_noirq are intended to save and restore the interrupt mask registers in the MBOX ICU0. However, the array used to store these registers was incorrectly sized, leading to memory corruption when accessing all four registers.

This commit corrects the array size to accommodate all four interrupt mask registers, preventing memory corruption during suspend and resume operations.

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.

Vulnerabilidad local (AV:L, PR:L) que corrompe memoria en el kernel de Linux; permite escalada de privilegios o ejecución de código arbitrario en el contexto del kernel durante operaciones de suspend/resume.

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.
