Description OSIDB Bzimport 2026-08-15 06:17:50 UTC 
In the Linux kernel, the following vulnerability has been resolved:

nvme-apple: Prevent shared tags across queues on Apple A11

On Apple A11, tags of pending commands must be unique across the admin
and IO queues, else the firmware crashes with
"duplicate tag error for tag N", with N being the tag.

Apply the existing workaround for M1 of reserving two tags for the admin
queue to A11.
