CVE-2026-92372
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.
