The S908U1UES2AVI5 firmware is out now for US unlocked S22 Ultras. It has the Oct 1 Android Security Patch level. Most carriers haven't released it yet, but you can get it via Frija using CSC=LRA. To see if your carrier has it OTA, check your carrier's website or sammobile.com.
The S before the bootloader number (S2AVI5) tells us that this update is only a security update.
[Mods: please edit the title to say S908U1. Thanks!]
