Vendor Solution
Upgrade to the patched release most closely related to your current version of BIND: BIND 9.16.33, BIND 9.18.7, BIND 9.19.5, or for BIND Supported Preview Edition (a special feature preview branch of BIND provided to eligible ISC support customers): BIND 9.16.33-S1.
Vendor Workaround
Disable the following algorithms in your configuration using the disable-algorithms option: ED25519, ED448. Note that this causes zones signed with these algorithms to be treated as insecure.

EUVD |
EUVD-2022-40774 | By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. |
