## What is CVE-2026-80632?

CVE-2026-80632 is a vulnerability in Linux, published on 28 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: mt76: mt7996: Fix NULL pointer dereference in mt7996_init_tx_queues()

When MT76_NPU and CONFIG_NET_MEDIATEK_SOC_WED are enabled and
mt76 detects properly the Airoha NPU SoC, mt7996_init_tx_queues() will
dereference a NULL WED pointer.
Fix the issue by always passing the WED pointer from mt7996_dma_init().

Check this codebase for CVE-2026-80632 and fix it if it is affected.

What it is: CVE-2026-80632 is a vulnerability in Linux, published on 28 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-2026-80632 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.
