CVE-2016-2059 Information

Description

The msm_ipc_router_bind_control_port function in net/ipc_router/ipc_router_core.c in the IPC router kernel module for the Linux kernel 3.x as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products does not verify that a port is a client port which allows attackers to gain privileges or cause a denial of service (race condition and list corruption) by making many BIND_CONTROL_PORT ioctl calls.
