CVE-2025-21992: HID: ignore non-functional sensor in HP 5MP Camera

In the Linux kernel, the following vulnerability has been resolved: HID: ignore non-functional sensor in HP 5MP Camera The HP 5MP Camera (USB ID 0408:5473) reports a HID sensor interface that is not actually implemented. Attempting to access this non-functional sensor via iio_info causes system hangs as runtime PM tries to wake up an unresponsive sensor. [453] hid-sensor-hub 0003:0408:5473.0003: Report latency attributes: ffffffff:ffffffff [453] hid-sensor-hub 0003:0408:5473.0003: common attributes: 5:1, 2:1, 3:1 ffffffff:ffffffff Add this device to the HID ignore list since the sensor interface is non-functional by design and should not be exposed to userspace.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel availability issue tied to a specific HP 5MP Camera USB device. The camera advertises a sensor interface that does not actually work. When userspace tries to access it, affected systems can hang. Business impact is likely limited to Linux devices with this hardware, but hangs can disrupt individual workstations or endpoints.

Executive priority

Treat as a targeted endpoint stability fix, not an emergency internet-facing vulnerability. Patch through normal kernel maintenance, with higher priority for fleets known to include affected HP camera hardware.

Technical view

The HP 5MP Camera with USB ID 0408:5473 exposes a HID sensor interface that is non-functional. Access through IIO sensor tooling can trigger runtime power management attempts to wake an unresponsive sensor, causing system hangs. The kernel fix adds this device to the HID ignore list so the bogus sensor is not exposed to userspace.

Likely exposure

Exposure appears hardware-specific: Linux systems using the HP 5MP Camera USB ID 0408:5473 on affected kernel versions or unpatched downstream builds. Servers and Linux endpoints without this camera are unlikely to be affected based on the supplied sources.

Exploitation context

No active exploitation is indicated. The CVE is not in KEV, and the supplied sources describe a local availability failure caused by accessing a misreported sensor interface, not remote code execution or privilege escalation.

Researcher notes

The public record lacks CVSS, CWE, and detailed affected-version ranges beyond kernel and stable references. Evidence supports a local denial-of-service style hang caused by runtime PM interaction with a non-functional HID sensor. Do not assume broader HID impact without vendor confirmation.

Mitigation direction

  • Apply kernel or distribution updates containing the HID ignore-list fix.
  • Check vendor guidance for your Linux distribution before deploying broadly.
  • Prioritize affected Linux endpoints with HP 5MP Camera USB ID 0408:5473.
  • Avoid intentional sensor probing on production systems until patched.

Validation and detection

  • Inventory Linux endpoints for HP 5MP Camera USB ID 0408:5473.
  • Confirm running kernels include the referenced stable fix or vendor backport.
  • Verify the non-functional sensor is no longer exposed after updating.
  • Review Debian LTS advisories if using Debian-maintained kernels.
