> There are important caveats and limitations to exploiting this latest vulnerability. As noted, some level of control over a local network is a prerequisite. That likely limits exploitation to insiders or attackers, such as nation-states or ransomware operators, who manage to gain low-level access inside a network and are looking for a way to elevate system rights.
This one seems weird. PXE-boot is such a fragile process in and off itself this doesn't strike me as end-of-the-world. If an attacker has enough presence on your network to send a targeted ICMP packet, they almost certainly could also fool around with your PXE-booting servers some other way.
