A flaw was found in svxlink's remotetrx NetUplink component. An unvalidated audio length field enables an out-of-bounds read, and when AUTH_KEY is not set, transceiver control functions are exposed to unauthenticated remote access. This allows unauthorized control of radio hardware connected to the svxlink system.
