CVE-2012-2137

Estado: ModificadaMedia (6.9)—

Desbordamiento de búfer en virt/KVM/irq_comm.c en el subsistema de KVM en el kernel de Linux antes de v3.2.24 que permite a usuarios locales provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de vectores relacionados con las interrupciones señalizadas por mensajes (MSI), entradas iRQ y un control incorrecto de la función setup_routing_entry antes de invocar la función kvm_set_irq.

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).
