This vulnerability, hidden within the netfilter: nf_tables component, allows local attackers to escalate their privileges and potentially deploy ransomware, which could severely disrupt enterprise systems worldwide.

You need to be able to run code on the system that has the bug. The bug is in the netfilter component, in how it’s managed on that system, not in the actual traffic flows.
So a non issue unless somebody has physical access to the machine?
Not directly, but as other comment has mentioned, it reduces the overall security posture because it could be combined with other flaws known and unknown.
Yeah, less vectors are better
Unfortunately, it’s not that simple, because attacks often involve “exploit chains”. In this case, an attacker would use a different vulnerability to gain code execution capability, and then use that capability to exploit this vulnerability.
Update your systems, folks.
