CVE-2019-19529

Published: 3 December 2019

In the Linux kernel before 5.3.11, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/net/can/usb/mcba_usb.c driver, aka CID-4d6636498c41.

From the Ubuntu security team

It was discovered that the Microchip CAN BUS Analyzer driver in the Linux kernel contained a use-after-free vulnerability on device disconnect. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
