Loading vulnerability…
CVE-2019-10207 is a null-pointer dereference in the Linux kernel Bluetooth UART flow-control handling function, hci_uart_set_flow_control. Crafted terminal-control ioctl operations against an affected Bluetooth device can cause the kernel to attempt instruction execution at the null address from a worker-thread context, resulting in a kernel crash. The issue affects vulnerable Linux kernel 3.x releases prior to 4.18.0 and affected 5.x releases.

This repository contains a proof-of-concept (PoC) exploit for CVE-2019-10207, a Linux kernel vulnerability in the Bluetooth HCI UART Marvell driver. The repository consists of a single C source file (CVE-2019-10207.c) and a README.md. The exploit works by opening the /dev/ptmx device, obtaining a pseudo-terminal, and issuing a series of ioctl calls to configure the line discipline and protocol for the Bluetooth HCI UART subsystem. Specifically, it sets the line discipline to N_HCI and the protocol to HCI_UART_MRVL, which triggers a kernel NULL pointer dereference if the system is running a vulnerable kernel (Linux 4.20.0) with the appropriate Bluetooth configuration options enabled. The exploit is local and requires the attacker to execute code on the target system. Its primary effect is to cause a denial of service by crashing the kernel. The README provides compilation instructions and notes the required kernel configuration options.
