# CVE-2026-111585: Integer Overflow in TeamViewer Remote Control Screen Decompression Leading to Heap-Based Buffer Overflow

Status: published. Published: 2026-10-27. Updated: 2026-11-04.

An integer overflow in the remote-control
screen processing component of TeamViewer clients (Full Client, Portable and Remote
Control App) prior to version 15.83 may allow a malicious remote host to cause
a denial of service or, depending on the platform, potentially execute
arbitrary code with the privileges of the viewer process. Exploitation requires
a user to establish a remote-control session to an attacker-controlled or
compromised host.
