…ing due to integer overflow Add validation in ppm_cmsg_nxthdr to ensure cmsg_aligned_len is at least sizeof(ppm_cmsghdr) after alignment calculation. This prevents an infinite loop when malformed ancillary data contains cmsg_len = 0xFFFFFFFFFFFFFFFF, which causes integer overflow in PPM_CMSG_ALIGN macro, resulting in cmsg_aligned_len = 0 and preventing forward progress in the loop.
