Description
In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79.
A flaw was found in the Linux kernel’s implementation for ADU devices from Ontrak Control Systems, where an attacker with administrative privileges and access to a local account could pre-groom the memory and physically disconnect or unload a module. The attacker must be able to access either of these two events to trigger the use-after-free, and then race the access to the use-after-free, to create a situation where key USB structs can be manipulated into corrupting memory.
