While the flaw does not provide direct code execution, the resulting memory disclosure could be leveraged by an attacker to compromise user data or leverage additional weaknesses."}}}}, "created": "2026-03-20T08:53:17.773714+00:00", "updated": "2026-03-25T14:09:45.800448+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
