CVE-2021-44769
An improper input validation vulnerability in the TLS certificate generation function allows an attacker to cause a Denial-of-Service (DoS) condition which can only be reverted via a factory reset.
Does this matter?
Lower severity and a low EPSS score (0.51%). Track it; it rarely justifies an emergency change on its own.
