A vulnerability was found in Linux Kernel 3.x (Operating System). It has been rated as critical. This issue affects the function msm_ipc_router_bind_control_port
of the file net/ipc_router/ipc_router_core.c of the component IPC router kernel Module. The manipulation with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. Impacted is confidentiality, integrity, and availability. The summary by CVE is:
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.
The weakness was published 05/05/2016 (Website). It is possible to read the advisory at codeaurora.org. The identification of this vulnerability is CVE-2016-2059 since 01/25/2016. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit.
