Samsung has published the details of its November 2026 security maintenance release for Galaxy phones and tablets, and it is one of the larger monthly patches of the year: fixes for more than 160 vulnerabilities across Android, Samsung’s own software and its Exynos hardware. The rollout itself has not started yet — Samsung says eligible devices will begin receiving it in the coming days — but the contents are now official. Here is what the update fixes and when your Galaxy is likely to get it.
Key Takeaways
- The patch combines Google’s November Android fixes with 24 Samsung-specific vulnerabilities (SVEs) and additional fixes for Samsung Semiconductor components such as Exynos chips and modems.
- The severity tally runs to 20 Critical, 141 High and 15 Moderate fixes — and all 20 Critical fixes come from Google’s side, including the critical Framework flaw CVE-2026-58868.
- Of Samsung’s 24 own fixes, 17 are publicly disclosed; the remaining 7 are being kept confidential until the update reaches more devices.
- Samsung’s fixes touch the bootloader, Contacts, Dialer, Messages, SIM lock and lock-screen calling, among other areas.
- This is a security release only — it is separate from the One UI 9 rollout and brings no new features.
What the November Patch Fixes
Samsung’s monthly release is a bundle from three sources. Google supplies the core Android fixes from its November 2026 security bulletin — the same bulletin that formally lists the ‘SMS of Death’ bug as Critical. Samsung Semiconductor contributes fixes for Exynos chipsets and modems. And Samsung’s mobile division adds its own Galaxy-specific patches.
Those Samsung-specific items (SVEs) are the part Galaxy owners cannot get anywhere else. This month’s disclosed list includes, among others:
- A bootloader flaw that could allow out-of-bounds memory writes by an attacker with physical access.
- A group of Samsung Contacts flaws rated Moderate, where a local attacker could potentially place calls without permission.
- Fixes around unauthorised lock-screen calling through widgets, SIM lock bypasses, and issues in the Dialer, Messages and MKV media playback.
Seven further Samsung fixes are deliberately not detailed yet. Samsung withholds them until the patch has reached more devices, so attackers cannot target phones that have not updated — standard practice for its monthly releases.
Is This the One UI 9 Update?
No — and the distinction matters this month, because both are moving at the same time. The One UI 9 rollout is Samsung’s big feature upgrade, working its way down the Galaxy range on its own schedule. The November security patch is a separate, much smaller maintenance release. Receiving One UI 9 does not automatically mean your phone already has the November patch, and the November patch does not bring One UI 9 features with it. You can check each independently: your One UI version and your Android security patch level are listed separately in Settings.
When Will Your Galaxy Get It?
Samsung has not published a device-by-device schedule for this patch. Based on its usual pattern:
- Recent flagships — the Galaxy S26 and S25 series and the latest foldables — typically receive monthly patches first.
- Older flagships and mid-range models follow over the following days and weeks.
- Timing varies by model, region and carrier, so two identical phones in different countries may not update on the same day.
To check manually, open Settings → Software update → Download and install. If nothing appears yet, the patch simply has not reached your model and region — Samsung details the release (formally, SMR Nov-2026 Release 1) before the rollout wave begins.
The Bottom Line
November is a heavy security month for Galaxy owners: over 160 fixes, 20 of them Critical, plus Galaxy-only patches for the bootloader, Contacts and lock-screen behaviour that only Samsung can ship. There is nothing to do today except know it is coming — when the update lands on your phone in the next few days, install it promptly, especially since seven of Samsung’s own fixes are being kept secret until enough devices are protected.

FAQs
When does Samsung’s November 2026 security update roll out?
Samsung has detailed the patch but the rollout had not begun when the details were published. Eligible Galaxy phones and tablets are expected to start receiving it in the coming days, with recent flagships first and timing varying by model, region and carrier.
How many vulnerabilities does the Samsung November 2026 patch fix?
More than 160 in total, combining Google’s November Android fixes, patches for Samsung Semiconductor components (Exynos chips and modems) and 24 Samsung-specific SVEs. The tally includes 20 Critical fixes — all from Google — plus 141 High and 15 Moderate.
Why are some of Samsung’s fixes not described?
Seven of Samsung’s 24 own fixes are kept confidential in the initial bulletin. Samsung withholds their details until the update has reached more devices, so the flaws cannot be targeted on phones that have not yet received the patch.
Is the November security patch the same as One UI 9?
No. One UI 9 is Samsung’s feature upgrade rolling out on its own schedule. The November 2026 security patch is a separate maintenance release with fixes only, and installing one does not mean you have received the other.
