Samsung has released its security bulletin for June 2026. According to this, the manufacturer is distributing important security patches for numerous Galaxy smartphones this month. The update should be rolled out gradually for all models that are still supported by the manufacturer. Samsung classifies five of the patched security vulnerabilities as "critical" and 28 as "high".
As the company writes on its security updates website, many of the patches come from Google, which are listed in the security bulletin for June 2026. Other patches affect only Samsung devices. The security vulnerabilities in the framework, kernel, and system endanger smartphones and tablets with Android 14, 15, 16, and 16 QPR2 – Samsung has been shipping the latter Android version with One UI 8.5 since May for many devices.
Critical vulnerabilities
The critical Bluetooth LE vulnerability (CVE-2026-0097), for example, allows attackers to escalate local privileges without requiring additional execution rights. No user interaction is required for exploitation, it says.

Another addressed vulnerability (CVE-2026-21352) made it possible, among other things, to write outside the permitted area, which could lead to the execution of arbitrary code. However, exploiting this vulnerability requires user interaction, where the victim must open a malicious file.
The June patch provides a total of 44 bug fixes for compatible Galaxy models, while models with Exynos processors receive an additional patch from Samsung Semiconductor. In addition to the patches delivered by Google and Samsung Semiconductor, Samsung Mobile provides 11.
The updates should be offered on many Galaxy devices in the coming days. Samsung further explains that the availability of security patches may vary depending on the region and model. Furthermore, only "important flagship models" receive monthly updates from Samsung, while other Galaxy devices are only supplied quarterly – Samsung also offers an overview for this.
