Analyst Note
Article [1] explicitly states this is a Google Chrome zero-day that was 'actively exploited' and 'fixed' by Google, meeting the core zero-day criteria. The 2021 CVE year aligns with the article timeline. While article [2] is about Microsoft, not Chrome, article [1] provides clear confirmation of active exploitation preceding or concurrent with the patch.
