CVE-2010-4165

Estado: ModificadaMedia (4.9)—💥 Exploit
The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel before 2.6.37-rc2 does not properly restrict TCP_MAXSEG (aka MSS) values, which allows local users to cause a denial of service (OOPS) via a setsockopt call that specifies a small value, leading to a divide-by-zero error or incorrect use of a signed integer.
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: 1.48%
Percentil entre todas las CVEs puntuadas: 73
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.
