CVE-2026-25954

CVE-2026-25954 affects FreeRDP. The vulnerability arises in the RAIL path where xf_rail_get_window returns a pointer from the railWindows hash table that is freed by the main thread while the RAIL channel thread is still using it, allowing dereferencing of a freed xfAppWindow pointer. This race c...
