CVE-2016-5870 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The msm_ipc_router_close function in net/ipc_router/ipc_router_socket.c in the ipc_router component for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allow attackers to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact by triggering failure of an accept system call for an AF_MSM_IPC socket.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
