## What is CVE-2026-68350?

CVE-2026-68350 is a memory corruption vulnerability in Linux, published on 10 Aug 2026. 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:

wifi: carl9170: fix OOB read from off-by-two in TX status handler

The bounds check in carl9170_tx_process_status() uses
`i > ((cmd->hdr.len / 2) + 1)` which is off by two, allowing
2 extra iterations past valid _tx_status entries when the firmware-
controlled hdr.ext exceeds hdr.len/2. Fix by using the correct
comparison `i >= (cmd->hdr.len / 2)`.

## Which versions are affected by CVE-2026-68350?

Check this codebase for CVE-2026-68350 and fix it if it is affected.

What it is: CVE-2026-68350 is a memory corruption vulnerability in Linux, published on 10 Aug 2026. 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-2026-68350 in the wild and no public exploit code.

Affected product: Linux. 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.
