Samsung has officially rolled out its June 2026 security patch, addressing 45 vulnerabilities across the Android operating system, its custom One UI interface, and Exynos processors. The update is scheduled to roll out in phases to eligible Galaxy devices over the coming weeks.

Of the system flaws addressed, five are marked as critical and 28 as high-risk within Google's core Android platform. Notably, this patch permanently resolves a hardware-related bug in the digital rights management (DRM) display driver affecting a wide range of Exynos chips—including the 1280, 2200, 1380, 1480, 2400, 1580, 2500, 1680, and 2600. This specific flaw was the primary culprit behind sudden kernel crashes during everyday use.

Alongside the core Android fixes, the South Korean tech giant patched 11 standalone security vulnerabilities within One UI and various system apps. In a push for transparency, Samsung publicly disclosed several major flaws, such as a permission error in the AppBlock feature that bad actors could exploit for unauthorized device access.

Several other core services have also been optimized to eliminate the risk of data leaks. These vulnerabilities were scattered across the dialer app, the SpriteWallpaper live wallpaper feature, the Galaxy Editing Service, and certain system settings components. Previous improper permission assignments could have allowed malicious apps to bypass security, access secure files, or silently trigger hidden features.

While Samsung has yet to announce a specific rollout schedule for individual models, users can manually check for the update by navigating to Settings > Software update and tapping Download and install. Early adopters may already have these fixes, as the security package was integrated into last month's One UI 9 beta release.
