Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

DNSSEC validation is not performed correctly. An attacker can cause this package to report successful validation for invalid, attacker-controlled records. Root DNSSEC public keys are not validated, permitting an attacker to present a self-signed root key and delegation chain.
