CVE-2026-97444

Estado: RecibidaAlta (7.7)—

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

ACPICA: add boundary checks in two places

Add boundary checks in acpi_ps_get_next_namestring() and acpi_ps_peek_opcode() to prevent out-of-bounds access.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
Puntuación base: 7.7

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.14%
Percentil entre todas las CVEs puntuadas: 3
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 principalT1499.004 Application or System Exploitationimpact60 %
Impacto secundarioT1005 Data from Local Systemcollection45 %

Vulnerabilidad local (AV:L, PR:N) en kernel Linux sin interacción necesaria. Falta de boundary checks sugiere lectura/corrupción de memoria. Alta confianza en T1068 por escalada potencial; impactos en DoS y acceso a datos según el daño de memoria.

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.
