# CVE-2025-21794

> 7.1 HIGH

## Beschreibung

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.
