Vulnerability details
The vulnerability allows a local user to execute arbitrary code.
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.
Affected software
Linux kernel
