| Subject: CVE-2025-21794: HID: hid-thrustmaster: fix stack-out-of-bounds read in usb_check_int_endpoints() |
| |
| 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. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
