Samsung delivers November update for Galaxy S21 series

Samsung has begun rolling out the November security patch to eligible Galaxy devices. Well, it has been pushing the latest security fixes as part of One UI 6.0 beta updates for some time, but devices running stable software (Android 13 or older) are now getting the update too. The Galaxy S21 series has had the privilege to kick things off this time.

Samsung pushes its November security update to the Galaxy S21

As of this writing, Samsung’s November SMR (Security Maintenance Release) is available for the Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra in Europe. The update is rolling out with the firmware build number G991BXXS9EWJO. The official changelog supplied by the company reveals that the package doesn’t contain anything more than this month’s security fixes. The OTA (over-the-air) download size comes in at 265MB for the Ultra mode (via SamMobile).

Samsung has already revealed that the November security update for Galaxy devices patches 65 vulnerabilities. These include five critical and over 40 high-severity Android OS issues, two high-severity Samsung Semiconductor patches, and 15 Samsung Vulnerabilities and Exposures (SVE) items. SVEs are security flaws that only affect the Korean firm’s Galaxy devices. These issues don’t exist on Android products from other brands.

According to Samsung, most of the SVEs patched this month are high-severity vulnerabilities. The company has fixed security issues with the USB Gadget Interface, FotaAgentm, SmsController, SecSettings, ChooserActivity, and other system apps, components, and services. Note that all 65 vulnerabilities patched with the November SMR don’t exist on every Galax device. However, every model is affected by at least one of these issues.

Samsung will gradually push these security fixes to more Galaxy devices, while simultaneously expanding the rollout for the Galaxy S21 series to other countries, including the US. If you’re using a Galaxy phone, you can check for new updates from the Software update menu in the Settings app. You may also get a notification when the OTA rollout hits your device.

A few A-series phones are also getting this update

Along with the Galaxy S21 series, Samsung has also released the November update for a few low-cost models. The Galaxy A03s, Galaxy A21s, and Galaxy M01 are getting the latest security fixes. The rollouts for these devices are scattered across various regions. The Korean firm should cover them globally with the November SMR over the next few weeks.
