Application crash via overlong Computer Name input

Published Mar 30, 2026 · Updated Mar 30, 2026

The Activate action processes a 240-character Computer Name value without enforcing the destination buffer's bounds, causing an out-of-bounds write. Exploitation requires local interaction with the graphical interface to paste the value and click Activate; only an application crash is demonstrated.
