  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: SOF: topology: validate vendor array size before parsing\n\nsof_parse_token_sets() reads array-\u003esize while iterating over topology\nprivate data. The loop condition only checks that some data remains, so a\nmalformed topology with a truncated trailing vendor array can make the\nparser read the size field before a full vendor-array header is available.\n\nValidate that the remaining private data contains a complete\nsnd_soc_tplg_vendor_array header before reading array-\u003esize.\n\nThe declared array size check also needs to remain signed. asize is an int,\nbut sizeof(*array) has type size_t, so comparing them directly promotes\nnegative asize values to unsigned and lets them pass the check,\nas reported in the stable review thread reference below.\n\nCast sizeof(*array) to int when validating the declared array size. This\nrejects negative, zero and otherwise too-small sizes before the parser\ndispatches to the tuple-specific code.",
