However, the iocb member is defined as a fixed-size 64-byte\narray within struct purex_item.\n\nIf the reported frame_size exceeds 64 bytes, subsequent memcpy calls will\noverflow the iocb member boundary. While extra memory might be allocated,\nthis cross-member write is unsafe and triggers warnings under\nCONFIG_FORTIFY_SOURCE.\n\nFix this by capping total_bytes to the size of the iocb member (64 bytes)\nbefore allocation and copying. This ensures all copies remain within the\nbounds of the destination structure member."
