CVE-2025-58147

Estado: AnalizadaAlta (7.5)—

[This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]

Some Viridian hypercalls can specify a mask of vCPU IDs as an input, in one of three formats. Xen has boundary checking bugs with all three formats, which can cause out-of-bounds reads and writes while processing the inputs.

Detalles técnicos trazas, registros y código del informe original
 * CVE-2025-58147.  Hypercalls using the HV_VP_SET Sparse format can
   cause vpmask_set() to write out of bounds when converting the bitmap
   to Xen's format.

 * CVE-2025-58148.  Hypercalls using any input format can cause
   send_ipi() to read d->vcpu[] out-of-bounds, and operate on a wild
   vCPU pointer.

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.

Vulnerabilidad de lectura/escritura fuera de límites en hipercalls de Xen expuestos en red (AV:N, PR:N, UI:N). Permite ejecución de código o escalada de privilegios en el hipervisor.

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.
