CVE-2026-72294

Estado: RecibidaAlta (8.8)—

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

LoongArch: KVM: Check irq validity in kvm_vcpu_ioctl_interrupt()

Function kvm_vcpu_ioctl_interrupt() can be called from userspace, here add irq validility cheking in kvm_vcpu_ioctl_interrupt().

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Puntuación base: 8.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.18%
Percentil entre todas las CVEs puntuadas: 6
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 %
Impacto secundarioT1498.001 Direct Network Floodimpact60 %

Vulnerabilidad de privilegios locales en KVM (AV:L/PR:L) sin interacción del usuario. El fallo en validación de IRQ permite escalada (S:C, C:H/I:H/A:H). Impacto: ejecución de código y DoS en hipervisor afectando máquinas virtuales.

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.
