Samsung has published its November 2026 security update for Galaxy phones and tablets, and it is one of the largest monthly patches of the year. The release bundles 155 fixes from Google's Android security bulletin with 24 of Samsung's own, and trackers that also count Samsung Semiconductor's chip-level items put the total above 200.

The headline flaw sits in Android itself. Google's November bulletin flags a critical Framework vulnerability, tracked as CVE-2026-58868, that could allow remote code execution without extra privileges and without any interaction from the phone's owner — no tap, no download, no permission prompt. It affects devices running Android 14 through Android 17.

Samsung's bulletin does not flag any of the flaws as already exploited in the wild, but a no-interaction remote bug is exactly the kind of hole attackers study first once a patch is public. That is why the size of this month's haul matters: all 20 critical fixes come from Google's side, alongside 134 high-severity fixes and a handful of moderate ones.

The worst bug needs no tap from you

Google splits its November Android fixes across two patch levels: 2026-11-01 covers 119 bugs, while 2026-11-05 adds 97 more in kernel and chip-vendor components from suppliers such as Qualcomm and MediaTek. Galaxy owners should look for the 2026-11-05 level for the full set. The Framework flaw is the one to worry about most, because it can be triggered remotely — the usual advice about not tapping suspicious links does not protect against it; only the patch does.

For scale, October's bulletin carried 45 Google fixes, nine of them critical. November's 155 Google fixes are more than three times that count, and the 20 critical fixes are more than double October's. It is a reminder that monthly patches are not routine housekeeping — some months, the gap between patched and unpatched is genuinely wide.

What Samsung fixed on its own phones

Samsung's own 24 items cover Galaxy-specific software and hardware. Seventeen are publicly described; seven are being kept private until more devices have the update, a standard move to avoid handing attackers a roadmap.

The high-severity Samsung items include an out-of-bounds write in the bootloader that needs physical access, a camera filter library flaw that could run code after user interaction, and a stack buffer overflow in a security library. The moderate items are more everyday: a SIM lock bypass caused by weak certificate checks, Contacts widgets that could place calls without permission, and memory bugs in the MKV video parser and Messages app.

Samsung Semiconductor's fixes target Exynos chipsets and modems — the silicon inside many Galaxy phones — which is why some trackers count the month's total above 200 rather than near 180. Either way, the count is unusually large.

When your Galaxy gets it — and what to do

Samsung has not published a rollout schedule; as usual, timing depends on model, carrier and region, with recent flagships such as the Galaxy S26 and Z Fold 7 typically first in line. Firmware trackers had recorded no November patch on monitored devices at the November 3 check, so most owners should expect the update to arrive over the coming days rather than immediately.

When it appears, install it the same day: open Settings, then Software update, and download it over Wi-Fi. The update carries fixes only — no new features, since One UI 9 already delivered those separately — so there is no reason to wait for a better moment. With a no-tap flaw in the mix, delay is the only real risk.
