The Samsung November 2026 security update is rolling out now, and it fixes more than 180 flaws across Galaxy software. If you own a recent Galaxy phone, you should check for it today rather than waiting for the automatic prompt.
Samsung published the bulletin on November 3 and refreshed its CVE list on November 5. Nothing in Samsung’s own list is rated Critical, but Google’s portion of the patch is large.
Here are the facts you need at a glance:
- Bulletin name: SMR Nov-2026 Release 1, published November 3, 2026
- Google fixes applied: 177 CVEs, including 20 rated Critical
- Samsung’s own fixes: 17 listed SVE items, plus 4 chipset CVEs
- Covers Android 14 through Android 17 software on supported Galaxy devices
- Cost: free, delivered over the air
That list is the short version. The sections below explain what it means for your phone.
What is in the Samsung November 2026 security update?
Samsung’s monthly bulletin mixes three kinds of fixes. The biggest chunk comes from Google’s Android Security Bulletin, which Samsung applies to its own builds. Then come Samsung’s private fixes, called SVE items, and patches for Samsung’s chipset hardware.
The table below breaks down what Samsung lists.
| Source | What was fixed | Severity |
|---|---|---|
| Google Android bulletin | 177 CVEs applied to Galaxy devices | 20 Critical, 156 High, 1 Moderate |
| Samsung SVE items | 17 listed items (the header says 24) | 3 High, 14 Moderate |
| Samsung Semiconductor | 4 CVEs | All High |
Samsung notes that 23 of Google’s CVEs do not apply to its devices, and two were already fixed in earlier updates. So the number you see here is already trimmed down to what matters for Galaxy phones.
We covered the Google side in more detail in our Android November 2026 security update guide, if you want the full Pixel-side picture.
Why the Critical Google patches matter most
Samsung’s own items are mostly Moderate, so the real urgency comes from the 20 Critical Google fixes. Critical bugs are the kind that can sometimes be abused without much action from you, depending on the flaw.
Samsung does not say any of these are being attacked in the wild. Still, once a patch is public, attackers can study it to find the bug. That is why installing quickly is the safe habit.
One detail is worth knowing: the SVE section header says 24 items, but only 17 are listed. Samsung says some items cannot be disclosed yet, so a few fixes may be hidden for now.
Which Galaxy phones will get it, and when?
Samsung says the bulletin covers “major flagship models” but does not publish a model list. Rollout order also varies by region and carrier.
Samsung adds that OS upgrades can delay security updates, and that some chipset patches may arrive in later packages. In plain terms, a phone that is mid-way through a big upgrade may get this patch a little later.
If you are waiting on a major version jump too, our One UI 9 rollout post explains how the schedule works.
How to install the update and check your patch level
Open Settings, tap Software update, then Download and install. Plug in your phone first and use Wi-Fi, since updates can be large.
After it finishes, go to Settings, About phone, Software information. Look for the security patch level. If it shows a November 2026 date, you have the new patch.
If the update is not showing yet, wait a few days and try again. Rolling out in waves is normal, and forcing it with unofficial files is not worth the risk.
What to do while you wait for the patch
Rollouts can take days or weeks, so a few habits help in the meantime. They cost nothing and cut your risk.
- Install apps only from the Play Store or Galaxy Store, and skip links sent in texts.
- Turn on Google Play Protect, which scans apps for known threats.
- Keep your apps updated, since many bugs are fixed there too.
These steps do not replace the patch. They just make it harder for a bad link or app to reach a weak spot while you wait.
Frequently Asked Questions
Is the Samsung November 2026 security update safe to install?
Yes. Security patches are small compared with full One UI upgrades, and skipping them leaves known bugs open. Back up important data first, as you would with any update.
Will my older Galaxy phone get it?
Samsung does not list models. Phones still inside their support window usually get patches, but older ones may only get them every few months. Check Software update to see.
Does this update add new features?
Not usually. Monthly security releases focus on fixes. Samsung’s bulletin does not mention new features for this one.
How do I know which patch level I have?
Go to Settings, About phone, Software information, and read the Android security patch level date.
My take: install this one when it appears. Twenty Critical Google fixes in a single month is a lot, and the update costs you only a few minutes and a restart. Don’t wait for a quiet week, because there is rarely a good reason to leave known holes open on the phone that holds your banking, photos, and messages.
