When header->size is less than sizeof(cmd->body) the\nunsigned subtraction wraps to nearly 4 GiB, producing a huge maxnum.\nAny user-controlled cmd->body.numVertexDecls then passes the bound and\nthe loop dereferences decl[i] far past the end of the kernel command\nbounce buffer, producing an out-of-bounds read of kernel memory.\n\nReject undersized headers up front.",
