CVE-2022-2795
By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service.
Does this matter?
Lower severity and a low EPSS score (2.29%). Track it; it rarely justifies an emergency change on its own.
