The May 2025 security update is rolling out for Google Pixel devices as of today, May 6, and it includes a critical patch for a zero-day security vulnerability. The update also includes three bug fixes and 28 total security patches for issues affecting Android and Google services. The company says that the May 2025 update’s rollout will continue over the next week, depending on your carrier and device model, so you might not see it immediately.

The Android Security Bulletin outlines the security issues addressed with this month’s Pixel update, including the zero-day exploit tracked as CVE-2025-27363. The bulletin notes that “there are indications that CVE-2025-27363 may be under limited, targeted exploitation.” Essentially, this means you should update your device as soon as the May 2025 patch is available to avoid falling victim to this security exploit.
The May 2025 security patch will also update your device’s bootloader to add anti-rollback measures. After updating, you won’t be able to run older versions of Android 15 on your device. This is likely in response to both the April and May patches including fixes for zero-day exploits.

After flashing the May 2025 update on these devices you won’t be able to flash and boot older Android 15 builds.”
