CWE-ID: CWE-664 - Improper control of a resource through its lifetime

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper resource management in the nvme-apple driver queue tag handling when submitting commands on Apple A11 systems. A local user can issue commands that trigger duplicate tag reuse across the admin and I/O queues to cause a denial of service.

The issue affects Apple A11 systems where pending command tags must be unique across the admin and I/O queues, and firmware may crash with a duplicate tag error.

Remediation

Install update from vendor's website.
