NewCVE-2026-109942  (opens in a new tab)
CWE-476  (opens in a new tab)

How to fix?

Upgrade freerdp/freerdp to version 3.32.0 or higher.

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference via rdg_process_close_packet in libfreerdp/core/gateway/rdg.c because rdg_process_control_packet accepts a header-only PKT_TYPE_CLOSE_CHANNEL packet and passes the null payload without a check. A malicious or compromised RD Gateway can send an eight-byte CLOSE_CHANNEL header to crash a connecting FreeRDP client.
