GrapheneOS also provides strong protection against these kinds of vulnerabilities being exploited before they're patched. You can also now obtain these patches earlier via our security preview releases, which provide the November 2025, December 2025 and January 2026 Android Security Bulletin patches already due to us having security partner access. This year, Android moved to a new model where there are up to 3 months of early access instead of 1 and it's now permitted to ship patches early without details or sources being posted until the embargo end date. Inability to post the sources we used until the embargo end date is why we added an opt-in security preview release system for this.
