CVE-2022-49278

Estado: AnalizadaAlta (7.1)—

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

remoteproc: Fix count check in rproc_coredump_write()

Check count for 0, to avoid a potential underflow. Make the check the same as the one in rproc_recovery_write().

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
Puntuación base: 7.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.27%
Percentil entre todas las CVEs puntuadas: 17
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation85 %
Impacto principalT1059 Command and Scripting Interpreterexecution75 %

AV:L PR:L UI:N indica acceso local con privilegios de usuario sin interacción. CWE-191 (Integer Underflow) en remoteproc permite manipular memoria. El impacto I:H A:H (integridad y disponibilidad altas) sugiere ejecución de código con escalada de privilegios local.

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.
