Описание
In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/hid/usbhid/hiddev.c driver, aka CID-9c09b214f30e.
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.
Отчет
This issue is rated as Moderate because of the need of physical access to the system.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
