AMD confirmed the issue earlier this week, attaching it to the external events client module (atieclxx.exe) in drivers 26.10.1 and 26.10.2. User reports put the write rate between 0.3 MB/s and 5 MB/s, which equates to about 26 GB to 432 GB per day on a machine that’s doing nothing. Until now, affected users had to disable the External Events utility, disable the resizable bar, or use a community-created open source tool that blocks writes. The release notes only mention the RX 7000 and newer versions for the idle fix, so it’s unclear if older Radeon cards were affected.

The driver comes with a fairly long list of known issues, including crashes or driver timeouts in Assassin’s Creed Black Flag Resynced, War Thunder, and Cyberpunk 2077, as well as visual corruption in Phantom Blade Zero and Call of Duty: Modern Warfare Remastered on RX 9000 cards. AMD also notes that Smart Access Memory can be disabled after installation on Windows 10, so anyone who has disabled Resizable Bar as a workaround workaround should ensure that it is re-enabled after the update. The full changelog is pasted below.
