Samsung has released a new software update for the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra units enrolled in the One UI 9.0 (Android 17) beta program in its home country, South Korea.

It has a size of 388.60MB and firmware version S91xNKSU8ZZI9. The brand says that this is a hotfix update, a small update released outside a normal schedule to fix a critical bug or security flaw.
