CVE-2025-21794 Information

Description

In the Linux kernel the following vulnerability has been resolved:

HID: hid-thrustmaster: fix stack-out-of-bounds read in usb_check_int_endpoints()

Syzbot[1] has detected a stack-out-of-bounds read of the ep_addr array from hid-thrustmaster driver. This array is passed to usb_check_int_endpoints function from usb.c core driver which executes a for loop that iterates over the elements of the passed array. Not finding a null element at the end of the array it tries to read the next non-existent element crashing the kernel.

To fix this a 0 element was added at the end of the array to break the for loop.
