# CVE-2026-92377: Local Privilege Escalation via DLL Sideloading in TeamViewer Patch Management for Windows

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

Improper access control in the Patch
Management update mechanism of TeamViewer Full Client and Host for Windows
prior to version 15.82 allows a local authenticated attacker with low
privileges to supply a signed executable through a forged IPC response and
cause it to load a malicious DLL from a user-writable temporary directory.
Successful exploitation results in arbitrary code execution with NT
AUTHORITY\SYSTEM privileges.
