What is CVE-2026-109679?

FreeRDP versions prior to 3.32.0 contain a vulnerability in the arm_handle_request_ok function. This flaw can be exploited when an ARM endpoint unexpectedly returns an empty HTTP 200 body, leading to a NULL pointer dereference. This issue enables attackers controlling the ARM gateway to send a zero-length response, which can cause the connecting client to crash, resulting in potential service disruption.
