CVE-2026-92377

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.
