Flaws That Are Being Detected

The two flaws that were being traced were CVE-2022-26522 and CVE-2022-26523. Avast released a new 22.1 version in February 2022 that was automatically applied to Avast and AVG installation customers to fix the issues. It is recommended that users use the premium version to patch immediately without automatic updates.
