## What is CVE-2024-58081?

CVE-2024-58081 is a medium-severity vulnerability in Linux kernel, published on 6 Mar 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:

clk: mmp2: call pm_genpd_init() only after genpd.name is set

Setting the genpd's struct device's name with dev_set_name() is
happening within pm_genpd_init(). If it remains NULL, things can blow up
later, such as when crafting the devfs hierarchy for the power domain:

  Unable to handle kernel NULL pointer dereference at virtual address 00000000 when read
  ...
  Call trace:
   strlen from start_creating+0x90/0x138
   start_creating from debugfs_create_dir+0x20/0x178
   debugfs_create_dir from genpd_debug_add.part.0+0x4c/0x144
   genpd_debug_add.part.0 from genpd_debug_init+0x74/0x90
   genpd_debug_init from do_one_initcall+0x5c/0x244
   do_one_initcall from kernel_init_freeable+0x19c/0x1f4
   kernel_init_freeable from kernel_init+0x1c/0x12c
   kernel_init from ret_from_fork+0x14/0x28

Bisecting tracks this crash back to commit 899f44531fe6 ("pmdomain: core:
Add GENPD_FLAG_DEV_NAME_FW flag"), which exchanges use of genpd->name
with dev_name(&genpd->dev) in genpd_debug_add.part().

Weakness: CWE-476 (NULL Pointer Dereference)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-58081 and fix it if it is affected.

What it is: CVE-2024-58081 is a medium-severity vulnerability in Linux kernel, published on 6 Mar 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-2024-58081 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.
