## What is CVE-2026-104944?

CVE-2026-104944 is a high-severity denial of service vulnerability in TP-Link Systems Inc. Tapo C500 v2.0, published on 6 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

TP-Link Tapo
C500 v2.0 contains an out-of-bounds function-pointer dispatch in its TDP
(TP-Link Device Protocol) daemon. A single unauthenticated UDP datagram can
cause an invalid indirect call, crashing the main service and resulting in a
denial-of-service condition.

Successful
exploitation may allow an unauthenticated attacker with network access to the
affected UDP service to repeatedly crash the TDP daemon, disrupting normal
device operation and availability. No authentication, session establishment, or
pairing is required to trigger the condition.

Weakness: CWE-823 (Use of Out-of-range Pointer Offset)

What it is: CVE-2026-104944 is a high-severity denial of service vulnerability in TP-Link Systems Inc. Tapo C500 v2.0, published on 6 Oct 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-2026-104944 in the wild and no public exploit code.

Affected product: TP-Link Systems Inc. Tapo C500 v2.0. 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.
