Samsung monthly updates: October 2026 security patch detailed

Samsung started rolling out the October 2026 patch to select phones a few days ago. It didn't say much about the patch then, but now the October 2026 security patch changelog has been revealed in full.

As usual, Samsung's October 2026 security update includes fixes released by Google, a.k.a. CVEs (Common Vulnerabilities and Exposures), as well as several fixes that Samsung has applied to its own software, hardware, and services. These are called SVEs (Samsung Vulnerabilities and Exposures).

In total, the October 2026 security patch includes the following number of vulnerability fixes:

CVE (Google fixes):

Low risk: none.

Moderate risk: 3 fixes.

High risk: 33 fixes

Critical: 9 fixes.

SVE (Samsung fixes):

Moderate risk: 7 fixes.

High risk: 6 fixes.

High-risk issues addressed by Samsung Semiconductor: 4 fixes.

You can read the full October 2026 patch changelog on Samsung's website. In the meantime, Samsung will continue rolling out the October 2026 update to more eligible devices, of which there are plenty.

First Samsung device: SGH-A800

Mihai is a blogger and column writer at SamMobile. His first Samsung phone was an A800 which took a lot of beating, and a part of him still misses the novelty of the clamshell design. In his free time, he enjoys watching shows, documentaries, and stand-up comedy; listening to music, taking walks, and occasionally playing old(er) video games.
