CVE-2026-107655

Estado: Pendiente de análisisMedia (4)—

Se encontró un fallo en CUPS. Al procesar comentarios de tickets de trabajo incrustados en documentos, el servicio maneja incorrectamente atributos IPP específicos, causando una desreferencia de puntero nulo no controlada. Un atacante no autenticado con permiso para enviar trabajos a una cola de impresora compartida puede enviar una solicitud de Protocolo de Impresión en Internet (IPP) manipulada para bloquear el demonio de impresión, resultando en una Denegación de Servicio (DoS) temporal para todos los servicios de impresión.

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.

AV:L sin UI:R sugiere T1068, pero el texto describe un crash remoto en cola compartida (DoS). El vector de acceso local es contradictorio con el ataque remoto descrito; se interpreta como acceso a la cola local del sistema. Impacto: null pointer dereference causa DoS de servicios de impresión.

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.
