| Subject: CVE-2022-48866: HID: hid-thrustmaster: fix OOB read in thrustmaster_interrupts |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| HID: hid-thrustmaster: fix OOB read in thrustmaster_interrupts |
| |
| Syzbot reported an slab-out-of-bounds Read in thrustmaster_probe() bug. |
| The root case is in missing validation check of actual number of endpoints. |
| |
| Code should not blindly access usb_host_interface::endpoint array, since |
| it may contain less endpoints than code expects. |
| |
| Fix it by adding missing validaion check and print an error if |
| number of endpoints do not match expected number |
| |
| The Linux kernel CVE team has assigned CVE-2022-48866 to this issue. |

| 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: |
