As a result,\nthe buffer allocated for the packet is 3 bytes too small and\nwrite_tag_66_packet() will write up to 3 bytes past the end of the\nbuffer.\n\nFix this by increasing the size of the allocation so the whole packet\nwill always fit in the buffer.\n\nThis fixes the below kasan slab-out-of-bounds bug:\n\n BUG: KASAN: slab-out-of-bounds in
