CVE-2022-28733
Description
Integer underflow in grub_net_recv_ip4_packets; A malicious crafted IP packet can lead to an integer underflow in grub_net_recv_ip4_packets() function on rsm->total_len value.

If the attack succeeds in such way, subsequent operations can write past the end of the buffer.
