CVE-2026-90229 Linux CVE debrief

Who should care

Linux kernel developers and administrators responsible for maintaining Linux systems, particularly those using Apple Mac mini (M1, 2020) systems, should review and apply patches, verify kernel versions, and monitor system logs. These individuals are critical to ensuring the security and stability of their systems. They should also be aware of the potential for system crashes or errors related to the nvme-apple module and take proactive measures to mitigate

Why it matters

A vulnerability in the Linux kernel's nvme-apple module can cause a crash when the controller fails to come up and is then torn down. Linux kernel developers and administrators should review and apply patches, verify kernel versions, and monitor system logs.

• Potential system crashes or errors related to the nvme-apple module
• Need to review and apply Linux kernel patches to destroy the admin queue on removal
• Verification of Linux kernel version and updates
• Monitoring system logs for potential issues

Technical summary

The Linux kernel's nvme-apple module has a vulnerability that can cause a crash when the controller fails to come up and is then torn down. The admin queue is allocated but never destroyed, leading to a potential NULL pointer dereference. This issue arises because the admin queue is not properly cleaned up during the removal process. To address this, developers should apply patches that ensure the admin queue is destroyed on removal. Additionally, verifying the Linux kernel version and monitoring system logs for potential issues are crucial steps in mitigating this vulnerability.

Defensive priority

Medium

Recommended defensive actions

• Review and apply the Linux kernel patches to destroy the admin queue on removal
• Verify the Linux kernel version and update if necessary
• Monitor system logs for potential crashes or errors related to the nvme-apple module
• Perform a thorough review of the system for any signs of exploitation
• Ensure that all necessary security updates are applied
• Consider implementing compensating controls for exposed systems
• Track exceptions and retest remediated assets

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, including a stack trace and references to the Linux kernel patches that resolve the issue. The vulnerability was introduced due to the admin queue being allocated but never destroyed in the nvme-apple module of the Linux kernel. This can lead to a crash when the controller fails to come up and is then immediately torn down. The issue is particularly relevant for Apple Mac mini (M1, 2020) systems. To verify and mitigate this vulnerability, defenders should review the N
