Описание
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/iowarrior.c driver, aka CID-edc4746f253d.
A use-after-free flaw was found in iowarrior_disconnect in iowarrior USB driver module were a flag was simultaneously modified causing a race between a device open and disconnect. This flaw could allow a physical attacker to cause a denial of service (DoS) attack. This vulnerability could even lead to a kernel information leak problem.
Меры по смягчению последствий
This flaw can be mitigated by preventing the affected USB IO-Warrior driver (iowarrior) kernel module from loading during the boot time, ensure the module is added into the blacklist file.
