CVE-2026-80769 Linux CVE debrief

A vulnerability in the Linux kernel's HID rapoo driver has been resolved. The vulnerability was caused by a missing hid_is_usb() check before calling to_usb_interface(). This could lead to a kernel splat in certain situations. Linux kernel developers and maintainers, Linux distribution maintainers, and users of Linux systems with the HID rapoo driver enabled should verify that their systems are up-to-date with the latest security patches and monitor system logs for potential kernel splats or other unusual activity.

Defensive priority

Medium

Recommended defensive actions

  • Review and apply the patch provided by the Linux kernel maintainers.
  • Verify that the system's Linux kernel is up-to-date with the latest security patches.
  • Monitor system logs for potential kernel splats or other unusual activity.
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review.
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented.
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.

Evidence notes

The CVE record and NVD entry provide information about the vulnerability, but details about exploitation or impact are limited. The vulnerability has been resolved with a patch. There is no evidence of exploitation in the wild, but Linux kernel developers and maintainers, Linux distribution maintainers, and users of Linux systems with the HID rapoo driver enabled should verify that their systems are up-to-date with the latest security patches and monitor system logs for potential kernel splats or other unusual activity.
