CVE-2026-72143

Estado: RecibidaAlta (7.1)—

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

platform/x86: ISST: Restore SST-PP control to all domains

The SST-PP control offset is only restored to power domain 0 after resume. During suspend, control values are read and stored for all power domains.

Use pd_info->sst_base instead of power_domain_info->sst_base, which only points to power domain 0 base address.

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.

Acceso local (AV:L) sin interacción (UI:N) con privilegios (PR:L). Fallo en restauración de controles SST-PP permite manipulación de dominio de potencia e inyección de fallos, causando corrupción de datos o denegación de servicio.

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.
