Deeper analysis
The vulnerability is a use-after-free flaw in the Service Worker API of Google Chrome versions prior to 103.0.5060.134. The issue is tracked as CWE-416 and carries a CVSS 3.1 score of 8.8, reflecting the potential for heap corruption when the affected API mishandles object lifetimes.
A remote attacker can exploit the flaw by convincing a user to visit a crafted HTML page, after which the use-after-free condition may be triggered to corrupt heap memory and potentially execute arbitrary code within the renderer process.
The official Chrome stable channel update released on 19 July 2022 upgrades the browser to version 103.0.5060.134 and resolves the issue. Downstream distributions such as Fedora have published corresponding package updates to address the same defect.
