In production builds where assertions are disabled, a userspace application that controls the length passed to a sendto syscall can supply an incomplete or truncated frame, causing socketcan_to_can_frame() to dereference fields beyond the end of the buffer. This results in an out-of-bounds read that can cause denial-of-service crashes or, because the parsed frame contents are transmitted on the network, leak adjacent memory."},{"lang":"es","value":"La implementación de SocketCAN valida la longitud de un búfer proporcionado por el usuario que contiene un objeto socketcan_frame utilizando únicamente una declaración NET_ASSERT en zcan_sendto_ctx() antes de desreferenciarlo en socketcan_to_can_frame(). En compilaciones de producción donde las aserciones están deshabilitadas, una aplicación en espacio de usuario que controla la longitud pasada a una llamada al sistema sendto puede proporcionar una trama incompleta o truncada, haciendo que socketcan_to_can_frame() desreferencie campos más allá del final del búfer.
