CVE-2026-92368 · Severity: high · CVSS 7.8 · Published 2026-09-29

TeamViewer Full Client and Host for Linux and macOS include a feature to play and convert recorded remote sessions stored in .tvs files. A flaw in how the application decompresses recorded session data can cause an out-of-bounds memory write. An attacker can craft a malicious session recording file that, when opened by a user through the playback feature, results in arbitrary code execution with the user's privileges.

## Technical details

The vulnerability is a heap-based buffer overflow (CWE-122) in the decompression logic for .tvs session recording files, affecting versions 15.70 through 15.81 on Linux and macOS. A size mismatch during decompression results in out-of-bounds heap writes. Exploitation requires user interaction: a victim must be tricked into opening a specially crafted .tvs file via the "Play or convert recorded session" feature, but no elevated privileges are required.
