CVE-2026-25942

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_rail_server_execute_result

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xf_rail_server_execute_result indexes the global error_code_names[] array (7 elements, indices 0-6) with an unchecked execResult-execResult value received from the server, allowing an out-of-bounds read when the server sends an execResult value of 7 or greater. Version 3.23.0 fixes the issue.
