Samsung November 2026 security patch details 160 fixes

Samsung has officially detailed its November 2026 security patch, addressing more than 160 vulnerabilities across the Android operating system and Galaxy-specific software and hardware components. This rollout coincides with the broader deployment of the One UI 9.0 update.

• The latest patch includes 155 Android security fixes from Google alongside 24 Galaxy-specific fixes from Samsung.
• Out of the total fixes, 17 vulnerabilities were publicly disclosed for transparency.
• Critical security flaws in Exynos chips, modems, and the bootloader have been resolved.
• Fixes also target lock screen calling issues, SIM lock bypasses, and core system apps.

Comprehensive Security Enhancements

As Samsung continues to expand the One UI 9.0 update to eligible Galaxy phones and tablets, maintaining regular monthly maintenance updates remains a top priority. The November bulletin provides a thorough breakdown of vulnerabilities patched across various layers of the software stack.

While Google's contribution covers the foundational Android OS with 155 fixes, Samsung's proprietary 24 patches ensure that custom hardware and software features unique to Galaxy devices remain protected against emerging threats.

Hardware and System Level Fixes

A significant focus of this month's patch is directed toward Exynos chipsets and internal modems. Securing these low-level hardware components is vital to preventing potential remote exploitation and ensuring stable network connectivity.

Additionally, the update addresses bootloader vulnerabilities, lock screen call exploits, and potential SIM lock bypass methods. These targeted fixes help prevent unauthorized physical and digital access to locked devices.

Impact on Users and Ecosystem

Regular monthly security updates are essential for safeguarding user data against modern exploits. Galaxy device owners are advised to install the November 2026 patch as soon as it becomes available through their system settings.
