CNA Information
Analyst Note
Article [1] explicitly names this as 'actively exploited Chrome zero-day bug' fixed by Google in 2021, confirming in-the-wild exploitation. The timing aligns with the CVE year (2021) and patch release, meeting zero-day criteria. Article [2] is a Microsoft Patch Tuesday article mentioning zero-days but does not appear to reference this Chrome CVE specifically.
