CVE-2011-1083
Estado: ModificadaMedia (4.9)—💥 Exploit
The epoll implementation in the Linux kernel 2.6.37.2 and earlier does not properly traverse a tree of epoll file descriptors, which allows local users to cause a denial of service (CPU consumption) via a crafted application that makes epoll_create and epoll_ctl system calls.
CVSS
- Versión: 2.0
- Vector: AV:L/AC:L/Au:N/C:N/I:N/A:C
- Puntuación base: 4.9
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.80%
- Percentil entre todas las CVEs puntuadas: 55
- Fecha de la puntuación: 7/10/2026
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).
💥 Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
