ASoC: SOF: topology: validate vendor array size before parsing
In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: topology: validate vendor array size before parsing sof_parse_token_sets() reads array->size while iterating over topology private data. The loop condition only checks that some data remains, so a malformed topology with a truncated trailing vendor array can make the parser read the size field before a full vendor-array header is available. Validate that the remaining private data contains a complete snd_soc_tplg_vendor_array header before reading array->size. The declared array size check also needs to remain signed. asize is an int, but sizeof(*array) has type size_t, so comparing them directly promotes negative asize values to unsigned and lets them pass the check, as reported in the stable review thread reference below. Cast sizeof(*array) to int when validating the declared array size. This rejects negative, zero and otherwise too-small sizes before the parser dispatches to the tuple-specific code.
