Description

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.

Executive Summary

This vulnerability affects the Linux kernel on Apple A11 devices. It involves shared command tags across admin and IO queues in the NVMe driver. If tags are not unique, the firmware crashes with a duplicate tag error.

Detection Guidance

This vulnerability is specific to Apple A11 devices using the Linux kernel's nvme-apple driver. Detection requires checking kernel logs for 'duplicate tag error for tag N' messages during NVMe operations. No standard network commands apply as this is a local system issue.

Impact Analysis

The vulnerability can cause system crashes on Apple A11 devices due to firmware errors. This may lead to data loss or denial of service if the NVMe storage becomes unresponsive.

Compliance Impact

This vulnerability does not directly affect compliance with standards like GDPR or HIPAA as it is specific to the Linux kernel's NVMe driver for Apple A11 hardware. It causes firmware crashes due to duplicate command tags but does not involve data exposure or privacy violations.

Mitigation Strategies

Apply the existing workaround used for M1 devices by reserving two tags for the admin queue on A11. This requires a kernel update or patch to the nvme-apple driver. Monitor vendor advisories for official fixes.
