## What is CVE-2026-93065?

CVE-2026-93065 is a vulnerability in Linux, published on 17 Sep 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: iwlwifi: fix counter type in iwl_fwrt_dump_error_logs

The loop counter 'count' was declared as u8 while num_pc is u32.
If firmware advertises more than 255 PC entries the counter wraps
back to zero and the loop never terminates potentially causing an
infinite loop or reading past the allocated pc_data array.

Change the declaration to u32 to match num_pc.

Check this codebase for CVE-2026-93065 and fix it if it is affected.

What it is: CVE-2026-93065 is a vulnerability in Linux, published on 17 Sep 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-2026-93065 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.
