CVE-2026-92372 · Severity: high · CVSS 8.8 · Published 2026-10-27

TeamViewer Full Client for Linux and macOS contains a flaw in its screen-image decoder that allows an attacker to write data outside the intended buffer boundaries. An attacker can exploit this by sending malicious screen data during a remote session or by tricking a user into opening a specially crafted TeamViewer recording file, leading to arbitrary code execution with the victim's privileges.
