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

> A local attacker can cause a system hang by accessing a non-functional HID sensor in the HP 5MP Camera driver, requiring a kernel patch.

- **Severity:** Medium 5.5 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H`)
- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Local or same network only
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 2 Apr 2025
- **Updated:** 11 May 2026
- **Also known as:** BELL-CVE-2025-21992, DEBIAN-CVE-2025-21992, GHSA-xc54-8222-cmjv, ROOT-OS-UBUNTU-2404-CVE-2025-21992, UBUNTU-CVE-2025-21992

## What is CVE-2025-21992?

CVE-2025-21992 is a medium-severity denial of service vulnerability in Linux kernel, published on 2 Apr 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

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.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-21992 and fix it if it is affected.

What it is: CVE-2025-21992 is a medium-severity denial of service vulnerability in Linux kernel, published on 2 Apr 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-21992 in the wild and no public exploit code.

Affected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
