I don't see how codecs_count could be greater than the control, since you
increment by one on each loop but >= is fine too I suppose.
Assume the payload from malicious firmware is packed like below
HFI_PROPERTY_PARAM_CODEC_SUPPORTED
HFI_PROPERTY_PARAM_CODEC_SUPPORTED
HFI_PROPERTY_PARAM_CODEC_SUPPORTED
.....
for 32 or more instances of above type
But you do this
cap = &caps[core->codecs_count++];
for each bit.
Anyway consider Dmitry's input re only calling this function once instead.
