CVE-2016-2059

High
Published: Translated: NVD NIST

Summary

The msm_ipc_router_bind_control_port function in the IPC router kernel module for Linux kernel 3.x does not verify that a port is a client port. This allows attackers to gain privileges or cause a denial of service by making many BIND_CONTROL_PORT ioctl calls.

Risk Assessment

Attackers can exploit this vulnerability to gain unauthorized privileges or trigger a race condition, leading to list corruption and denial of service, which can severely impact system stability.

Recommendation

It is recommended to update the Linux kernel to a version that fixes this vulnerability and to monitor ioctl calls for potential attack attempts.
