FreeRDP has heap-use-after-free in xf_rail_server_local_move_size

CVE-2026-25954

Description

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xf_rail_server_local_move_size dereferences a freed xfAppWindow pointer because xf_rail_get_window returns an unprotected pointer from the railWindows hash table, and the main thread can concurrently delete the window (via a window delete order) while the RAIL channel thread is still using the pointer. Version 3.23.0 fixes the issue.
