CVE-2026-92372

Out-of-bounds Write in TeamViewer Full Client for Linux and macOS Allows Remote Code Execution

Assigner: TV
Reserved: 16.09.2026 Published: 27.10.2026 Updated: 27.10.2026

An out-of-bounds write vulnerability in the screen-image decoder of TeamViewer Full Client for Linux and macOS prior to version 15.83 allows a remote attacker to execute arbitrary code by supplying crafted screen-image data during a remote-control session. The vulnerability can also be exploited by persuading a user to open a specially crafted TeamViewer session recording (.tvs). Missing destination bounds checking in the decoder allows crafted screen-image data to cause an out-of-bounds write to the image buffer. Exploitation requires user interaction.
