CVE-2017-16525

Published: 3 November 2017

The usb_serial_console_disconnect function in drivers/usb/serial/console.c in the Linux kernel before 4.13.8 allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device, related to disconnection and failed setup.

From the Ubuntu Security Team

Andrey Konovalov discovered a use-after-free vulnerability in the USB serial console driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
