macOS Big Sur 11.5.1 (build 20G80) released (security fix)
Includes security fix for a vulnerability being exploited.
Info from what's new in macOS Big Sur 11.5.1:
"macOS Big Sur 11.5.1 provides important security updates and is recommended for all users."
Make sure you have a backup before updating. I reboot and update with no apps running. If using any 3rd party Security software or VPN, disable or remove it before updating, and make sure you have adequate free space on the volume. (Apple doesn't list required space for OS updates, but lists 26GB or more for upgrades from macOS Sierra or later.) If you have trouble installing the update, try updating from Safe Mode. If all else fails, try downloading the full macOS install from the App store.

A M1 Mini owner running Big Sur 11.5 said software update listed the 11.5.1 update as 2.2GB, but the actual 11.5.1 update download was 3.11GB. She installed both 11.5 and 11.5.1 updates in Safe Mode. (M1 Mini firmware version still 6723.140.2.)

You can check Apple's Big Sur forum for feedback. (Posts may be in previous problem threads.)
And for M1 owners, also check the Mac Mini, iMac, MacBook Pro, & MacBook Air forums.

iOS 14.7.1, iPadOS 14.7.1, watchOS 7.6.1 released (includes security fix)
