Doc Text:
A vulnerability was found in hiddev_open in drivers/hid/usbhid/hiddev.c in the USB Human Interface Device class subsystem, where an existing device must be validated prior to its access. The device should also ensure the hiddev_list cleanup occurs at failure, as this may lead to a use-after-free problem, or possibly escalate privileges to an unauthorized user.

Description msiddiqu 2019-12-13 20:29:51 UTC 
A vulnerability was found in hiddev_open in drivers/hid/usbhid/hiddev.c  in USB human interface device class  subsystem,  in this problem if a USB device fails to initialize correctly list management code in the error handling path can delete a list entry while other USB code paths could be using it.  This may lead to a use-after-free situation which is frequently used by attackers to corrupt memory, panic the system or possibly escalate privileges.
