## What is CVE-2026-92368?

CVE-2026-92368 is a high-severity memory corruption vulnerability in TeamViewer Full Client, published on 29 Sep 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

TeamViewer Full Client and Host for Linux and macOS prior version 15.82 contain a heap-based buffer overflow vulnerability in the processing of .tvs session recording files. A size mismatch during decompression of recorded session data can result in out-of-bounds heap writes. By convincing a user to open a specially crafted session recording through the "Play or convert recorded session…" feature, an attacker may achieve arbitrary code execution with the privileges of the current user

Weakness: CWE-122 (Heap-based Buffer Overflow)

What it is: CVE-2026-92368 is a high-severity memory corruption vulnerability in TeamViewer Full Client, published on 29 Sep 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-92368 in the wild and no public exploit code.

Affected product: TeamViewer Full Client. 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.
