Descriptions
Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel before 4.6.3 allows local users to cause a denial of service (double free) or possibly have unspecified other impact via a crafted application that makes sendmsg system calls, leading to a free operation associated with a new dump that started earlier than anticipated.
Condición de carrera en la función netlink_dump en net/netlink/af_netlink.c en el kernel de Linux en versiones anteriores a 4.6.3 permite a usuarios locales provocar una denegación de servicio (liberación doble) o posiblemente tener otro impacto no especificado a través de una aplicación manipulada que realiza llamadas al sistema sendmsg, conduciendo a una operación libre asociada con un nuevo volcado que comenzó antes de lo anticipado.
A double free vulnerability was found in netlink_dump, which could cause a denial of service or possibly other unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
