What it is
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.
Description quoted from the CVE record (assigned by TV, published 2026-10-27).
Weakness: CWE-190 Integer overflow or wraparound
