CVE-2022-48866: HID: hid-thrustmaster: fix OOB read in thrustmaster_interrupts

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

Analyst readout for executives and security teams

Plain-English summary

CVE-2022-48866 is a Linux kernel HID driver flaw in Thrustmaster device handling. The driver could read past available USB endpoint data because it did not verify the actual endpoint count. Public sources show a kernel fix, but provide no CVSS score or confirmed active exploitation.

Executive priority

Treat this as a kernel maintenance issue with higher urgency for workstations, labs, kiosks, or industrial systems exposed to untrusted USB devices. There is no cited evidence of active exploitation, but kernel memory-safety bugs should be cleared through normal patch governance.

Technical view

The issue is an out-of-bounds read in the Linux kernel hid-thrustmaster path, reported by syzbot. The root cause is missing validation before accessing usb_host_interface::endpoint. Stable kernel commits add endpoint-count validation and return an error when the expected endpoint layout is not present.

Likely exposure

Exposure is most relevant to Linux systems running affected kernel builds with the hid-thrustmaster driver reachable through USB HID device handling. The source bundle lists Linux kernel versions including 5.13, 5.15.29, 5.16.15, and 5.17 as affected, but does not provide distribution-specific package status.

Exploitation context

The sources do not report active exploitation, and the CVE is not marked KEV. Evidence points to a malformed or unexpected USB HID interface causing an out-of-bounds read during driver probing or interrupt setup. Practical exploitability and security impact are not fully described in the provided sources.

Researcher notes

The strongest evidence is the kernel commit description: syzbot found a slab out-of-bounds read, caused by trusting endpoint array length. The provided data lacks CVSS, CWE, exploitability analysis, and distro package mapping, so impact should be validated against the exact kernel branch in use.

Mitigation direction

  • Update to a Linux kernel build containing the referenced stable fixes.
  • Check your Linux distribution advisory for exact fixed package versions.
  • Limit exposure to untrusted USB HID devices where operationally feasible.
  • Prioritize systems that allow physical or peripheral device access.

Validation and detection

  • Inventory Linux hosts and kernel versions against vendor advisories.
  • Check whether hid-thrustmaster is present, built, or loadable on relevant systems.
  • Confirm installed kernel includes one of the referenced stable fixes.
  • Review endpoint-validation changes in downstream kernel patches if using custom kernels.
