Google Chrome for Android: Use after free in Notifications
Summary
A use-after-free vulnerability in the Notifications component of Google Chrome for Android before 156.0.8078.47 allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker needs a victim to open a crafted HTML page, for example through a phishing link or a compromised website, but no login is required. Chromium rates the issue as Medium severity, and no exploitation has been reported. Some root-cause details differ between sources and remain unconfirmed.
