Samsung’s June 2026 security patch addresses 5 critical and 28 high-severity Android OS issues. It also fixes a semiconductor vulnerability affecting Exynos chips, including Exynos 1280, 2200, 1380, 1480, 2400, 1580, 2500, 1680, and 2600. The issue is a Use-After-Free bug in the Exynos DRM HDR driver that caused a kernel crash.

Furthermore, Samsung has fixed 11 Samsung Vulnerabilities and Exposures (SVEs) discovered within One UI and system apps. To improve user confidence in the security segment, the company has disclosed some of its SVE items. One high-severity issue involves improper authorization in AppBlock that could allow a local attacker to perform arbitrary actions.

Samsung also highlights several moderate-severity issues in core system services. One issue in Telephony allows attackers to access sensitive information due to incorrect privilege assignment. Another issue affects SpriteWallpaper, where improper export of app components could allow attackers to access sensitive data.

The company also pointed out a vulnerability in SecTelephonyProvider that could expose privileged files. In Galaxy Editing Service, improper component export could allow attackers to execute privileged operations. An issue in MediaTek Audio HAL allows unauthorized triggering of privileged functions. Other issues were discovered in components like ImsSettings and AuditLogService.

There’s no word when Samsung plans to begin pushing its June 2026 security update for eligible Galaxy devices. However, based on previous releases, the update should not take long to reach users. You can check for it by navigating to Settings > Software update > Download and install. It is worth mentioning that the company bundled this month’s patch with its second One UI 9 beta, which was released last month.
