Descriptions

The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel through 4.9.11 mishandles DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allows local users to obtain root privileges or cause a denial of service (double free) via an application that makes an IPV6_RECVPKTINFO setsockopt system call.

La función dccp_rcv_state_process en net/dccp/input.c en el kernel de Linux hasta la versión 4.9.11 no maneja adecuadamente estructuras de paquetes de datos DCCP_PKT_REQUEST en el estado LISTEN, lo que permite a usuarios locales obtener privilegios root o provocar una denegación de servicio (liberación doble) a través de una aplicación que hace una llamada de sistema IPV6_RECVPKTINFO setsockopt.

A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system.
