CVE-2026-25952: 
NixOS vulnerability analysis and mitigation

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xf_SetWindowMinMaxInfo dereferences a freed xfAppWindow pointer because xf_rail_get_window in xf_rail_server_min_max_info 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.
