CVE-2015-5366

Estado: ModificadaMedia (5)—
Vulnerabilidad en las funciones (1) udp_recvmsg y (2) udpv6_recvmsg en el kernel de Linux en versiones anteriores a 4.0.6, proporcionan valores de retorno -EAGAIN inapropiados, lo que permite a atacantes remotos causar una denegación de servicio (interrupción de lectura de EPOLLET en aplicación epoll) a través de una suma de comprobación incorrecta en un paquete UDP, una vulnerabilidad diferente a CVE-2015-5364.
CVSS
