CVE-2022-34294
This allows DNS cache poisoning because there is not enough entropy to prevent traffic injection attacks.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.85%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
