A\ntruncated record can therefore make those reads exceed the blob.\n\nThe same record also supplies addresses and lengths for writes into\nDPRAM. The generic loader uses wrap-prone mixed signed arithmetic for its\nbounds check, while the application loader does not bound the staging\ncopy at all.\n\nPass the firmware end to the parser and validate the full source record.\nUse a signed wide offset for generic DPRAM records and validate the\napplication staging span against the mapped DPRAM before copying."
