Samsung November 2026 Update: 179 Security Fixes for Galaxy
Your friend has a Galaxy S26 just like yours. A small security update reached their phone a few days ago, while yours still says the software is up to date. This happens every month with Samsung, and it is rarely a fault. This month's patch is worth chasing, though, because it closes close to 180 vulnerabilities, some of them rated critical.
In short: Samsung published its monthly security bulletin on November 3, 2026. According to SamMobile, the Samsung November 2026 update contains about 179 fixes: 155 Android vulnerabilities from Google and 24 Galaxy-specific flaws. The rollout started with the Galaxy S26 series, reports say it has reached the Z Fold 7 and Z Flip 7, and you install it from Settings, then Software update.
What is in Samsung's November 2026 update?
Every month, Samsung bundles two kinds of fixes into one package: Android platform vulnerabilities disclosed by Google, and flaws in One UI and Samsung's own apps, which carry an SVE identifier. This is a security-only release, so there are no new features. Its value lies in what it prevents, not in anything you will see on screen.
| Item | Details per SamMobile and Samsung's bulletin |
|---|---|
| Google Android fixes | 155 vulnerabilities |
| Galaxy-specific fixes (SVE) | 24, with details published for 17 and the rest withheld for now |
| Critical vulnerabilities | 20, all in Google's portion |
| Samsung Semiconductor fixes | 4 high-severity issues |
| Bulletin date | November 3, 2026, revised on November 5 |
Figures vary a little between outlets, and some reported more than 200 fixes. We use SamMobile's tally, which is built from the official bulletin: 155 from Google and 24 from Samsung.
Key vulnerabilities this update closes
Samsung has not said that any of its own flaws were exploited in real attacks, and the bulletin lists them all as privately reported. That is no reason to wait: once details are public, patched flaws become easier targets for anyone who has not updated. Notable fixes include:
- A bootloader flaw: an out-of-bounds memory write rated high severity that requires physical access to the phone. Its real risk shows up if your phone is stolen or ends up in someone else's hands.
- A camera plugin library flaw: an input validation weakness that could let a malicious app run code, provided the user interacts with it.
- A security library flaw: a stack buffer overflow that could allow local code execution.
- Call log and Contacts widgets: several permission flaws that could allow calls to be placed without authorization, including one tied to the cover screen widget on foldables.
- SIM lock bypass: a certificate validation flaw that could let a party with local privileges get around the SIM lock.
- Messages and Phone apps: flaws that could expose some data to other apps on the device.
Most of these are "local" bugs: they need an app already installed on your phone, or physical access to it. Your best defense remains not installing apps from unknown sources, as the case of the malicious app that targeted WhatsApp backups on Android showed.
The physical-access flaws, such as the bootloader bug and the SIM lock bypass, are a reminder that protection is not only about software. Use a strong screen lock, a PIN of six digits or more rather than a simple pattern, and turn on the find-my-phone service in your Samsung or Google account so you can lock or wipe the device remotely if it goes missing. It takes two minutes.
Which phones get the update?
Samsung's bulletin does not list models. It refers only to "major flagship models" and notes that timing varies by region and model. Based on reports available as of November 12:
| Group | Models | Reported status |
|---|---|---|
| S26 series | Galaxy S26, S26+, S26 Ultra | Rolling out |
| 2026 foldables | Galaxy Z Fold 7, Z Flip 7 | Reported as rolling out |
| S25 series | S25, S25 FE | Expected in the coming days |
| Previous foldables | Z Fold 6, Z Flip 6 | Expected |
| Mid-range | Selected A and M series models | Expected, no dates given |
The last three rows come from unofficial reports, and Samsung has not confirmed specific dates. Samsung also notes that some chipset fixes may ship in a later package, so two phones of the same model can show the same patch level without being identical underneath.
How to install the Samsung November 2026 update
- Charge the phone to at least 50% and connect to Wi-Fi.
- Open Settings and scroll down to Software update.
- Tap Download and install, then wait for the download to finish.
- Tap Install now.
- After the restart, go to Settings, About phone, Software information, and check that Android security patch level shows November 2026.
One extra tip: on the same page, turn on automatic download over Wi-Fi so you do not miss future months. Also check Google Play system update under the security section, since it is a separate channel that delivers other fixes.
Update not showing up? What to do
- Give it a few days: Samsung rolls out updates in waves, often starting in South Korea before Europe and other regions.
- Carrier-locked phones: some operator versions lag behind because they go through extra testing.
- Check manually: do not rely on the notification alone. Open the Software update page every two or three days.
- Avoid update files from random sites: any "update file" sent through a link or a third-party app may be a trap. The only safe routes are Software update in Settings or Samsung's official Smart Switch.
- Older phone out of support: if updates stopped entirely months ago, your phone may have reached the end of its security support. Being careful about which apps you install matters even more then.

FAQ
Does the Samsung November 2026 update add new features?
No. It is a monthly security release. It may include minor stability fixes, but nothing you will notice as a new feature.
How big is the update, and will it erase my data?
Size depends on the model and region, and Samsung has not published it. Official updates through Settings do not wipe your data, though backing up before any update is a good habit.
Is there an exploited flaw I should worry about right now?
Samsung's bulletin does not flag active exploitation for any of its own vulnerabilities this month. Even so, 20 critical issues are reason enough to install it as soon as it appears.
How do I check my phone's security patch level?
Go to Settings, About phone, Software information, and look at Android security patch level.
The bottom line
Samsung's November patch looks routine but closes a lot of holes. If it has reached you, install it today. If not, do not go hunting for it on outside websites; just check Software update every few days. The same logic applies to your computer, as we explained in our look at Microsoft's October 2026 Patch Tuesday: a delayed update is what lets attackers in.
