What is CVE-2022-34293?

The wolfSSL library, prior to version 5.4.0, has a vulnerability that permits remote attackers to trigger a denial of service condition via a specific manipulation of DTLS (Datagram Transport Layer Security). This occurs when the server incorrectly skips a crucial step involving return-routability checks, potentially leading to service disruption and unavailability.
