CVE-2010-4249
La función wait_for_unix_gc de net/unix/garbage.c en el kernel de Linux en versiones anteriores a la 2.6.37-rc3-next-20101125 no selecciona apropiadamente el momento de recolectar la basura de los sockets en uso; lo que permite, a usuarios locales, provocar una denegación de servicio (cuelgue del sistema) a través del uso modificado de las llamadas al sistema "socketpair" y "sendmsg" de los sockets SOCK_SEQPACKET.
CVSS
- Puntuación base
- 4.9
- Versión
- 2.0
- Vector
- AV:L/AC:L/Au:N/C:N/I:N/A:C
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días
- 0.89 %
- Percentil entre todas las CVEs puntuadas
- 59
- Fecha de la puntuación
- 20/10/2026
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.
