Samsung has started rolling out their March SMR (Security Maintenance Release) for the Galaxy S23 Plus. Other devices from this series, including the Galaxy S23 and Galaxy S23 Ultra, have already received the March security patch. This update is gradually rolling out and weighs around 350MB through an OTA update with a firmware build of S91*U1UES1AWBM.

However, this update doesn’t seem to add any new features to the device. It should be mentioned that you can expect new features to come with future updates in the coming months. The update will first arrive on unlocked versions of the Galaxy S23 Plus and then will roll out to carrier-locked versions, including AT&T, T-Mobile, and Verizon.

This update is more about fixing vulnerabilities. Samsung fixed 11 vulnerabilities, while Google patched 39 vulnerabilities, making 50 vulnerability fixes. Five of these fixes were critical, 35 were high, none were moderate, and three were already fixed, while five were not applicable.
