It is triggered by loading a crafted HTML page, which can lead the browser to overwrite adjacent heap memory.

While the risk of exploitation is considered low due to the prevailing low EPSS, the potential impact of heap corruption warrants active mitigation."}}}}, "created": "2026-03-20T08:53:28.166238+00:00", "updated": "2026-03-25T14:09:58.065245+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
