- **Exploited in the wild:** Not known
- **Fix available:** Yes
- **Published:** 16 Jul 2024
- **Updated:** 11 May 2026

## What is CVE-2022-48794?

CVE-2022-48794 is a medium-severity vulnerability in Linux kernel, published on 16 Jul 2024. 

### Official description

In the Linux kernel, the following vulnerability has been resolved:

net: ieee802154: at86rf230: Stop leaking skb's

Upon error the ieee802154_xmit_complete() helper is not called. Only
ieee802154_wake_queue() is called manually. In the Tx case we then leak
the skb structure.

Free the skb structure upon error before returning when appropriate.

As the 'is_tx = 0' cannot be moved in the complete handler because of a
possible race between the delay in switching to STATE_RX_AACK_ON and a
new interrupt, we introduce an intermediate 'was_tx' boolean just for
this purpose.

There is no Fixes tag applying here, many changes have been made on this
area and the issue kind of always existed.

Weakness: CWE-401 (Missing Release of Memory after Effective Lifetime)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2022-48794 and fix it if it is affected.

What it is: CVE-2022-48794 is a medium-severity vulnerability in Linux kernel, published on 16 Jul 2024. 
Exploitation: There is no known exploitation of CVE-2022-48794 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.
