# CVE-2024-53682: regulator: axp20x: AXP717: set ramp_delay

> Missing ramp delay configuration in the AXP717 regulator driver causes system crashes during CPU DVFS operations, leading to denial of service.

- **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:** 11 Jan 2025

- **Also known as:** BELL-CVE-2024-53682, DEBIAN-CVE-2024-53682, GHSA-77pj-c5wq-j7q7, UBUNTU-CVE-2024-53682

## What is CVE-2024-53682?

CVE-2024-53682 is a medium-severity denial of service vulnerability in Linux kernel, published on 11 Jan 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:

regulator: axp20x: AXP717: set ramp_delay

AXP717 datasheet says that regulator ramp delay is 15.625 us/step,
which is 10mV in our case.

Add a AXP_DESC_RANGES_DELAY macro and update AXP_DESC_RANGES macro to
expand to AXP_DESC_RANGES_DELAY with ramp_delay = 0

For DCDC4, steps is 100mv

Add a AXP_DESC_DELAY macro and update AXP_DESC macro to
expand to AXP_DESC_DELAY with ramp_delay = 0

This patch fix crashes when using CPU DVFS.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-53682 and fix it if it is affected.

What it is: CVE-2024-53682 is a medium-severity denial of service vulnerability in Linux kernel, published on 11 Jan 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-2024-53682 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.
