The latest security update for the Galaxy S23 lineup is now getting a wider rollout, following its limited release in the US earlier this month. This is the second new security update for the Galaxy S23, S23+, and S23 Ultra since the three phones were updated to Android 14/One UI 6.
The December update for the Galaxy S23 series sports a firmware version ending in BWKC, though this may be different for you depending on when the update arrives in your country. Right now, it is rolling out in a dozen or so markets, and more countries will get it over the coming days.
The December update only brings a newer security patch; everything else will remain the same as it was on the previous version of Android 14, so you may have to wait for future updates if you're hoping to get fixes for issues that you may be facing in One UI 6.0.

The December security patch brings a total of 75 fixes for known vulnerabilities. 54 of them affect the core Android OS, 16 affect Samsung One UI, and the rest tackle vulnerabilities affecting Galaxy devices with some specific Exynos processors under the hood. Naturally, the last one isn't a concern for the Galaxy S23 series, as all three models are powered by the Snapdragon 8 Gen 2 chip worldwide.
You can download the update on your Galaxy S23, S23+, or S23 Ultra from its Settings » Software update menu. Alternatively, download the latest firmware from the SamMobile archive and install it on the phone using a Windows PC.
Author's note: The December update for the Galaxy S23 series could be followed by the One UI 6.1 update. Samsung has begun development on One UI 6.1 for the Galaxy S23 lineup and will likely start rolling it out soon after the Galaxy S24 hits retail shelves in late January.
