  Download Pages for these Updates
• Download Security Update 2021-002 Catalina (1.79 GB)
• Download Security Update 2021-003 Mojave (1.79 GB)

You can check for feedback in Apple's Mojave and Catalina forums.
(Some use the download updater and install from a Safe Mode boot.)

FYI: Posts in Apple's Mojave forum on Security Update 2021-003 fails with ERROR_7E7AEE96CA displayed in dialog with Catalina install "badge". (Mentions cause was using Mojave as a migration source for Catalina on a separate boot partition, leaving the source Mojave volume with a Catalina restore partition. A suggestion was installing macOS 10.14.6 Combo Update, then applying later updates, but this later reply did a fresh install of Mojave on a new partition instead.)
 

This release also fixes the following issues:
• External 4K monitors may not display in full resolution when connected over USB-C.
• Login window may not display properly after restarting Mac mini (M1, 2020).
• Reminders created via Siri may be unintentionally set for early morning hours.
• iCloud Keychain might not turn off.
• AirPods audio routing to incorrect device for Automatic Switching.
• AirPods Automatic Switching notifications might be missing or duplicated.
• The Dwell feature may not work in the Accessibility Keyboard.

If you have trouble installing the update, try updating from Safe Mode.
And if running any 3rd party Security software, disable it before updating.

It's not listed but hopefully this fixes the CVM Server crashes on M1 Macs since v11.2 update.
(Example Apple forum threads here, here & here. Appears related to OpenGL.framework.)
