CVE-2026-53104 Linux CVE debrief

Who should care

Linux kernel maintainers, users, and administrators, especially those using affected kernel versions, should review and apply patches to prevent potential memory leaks. They should also monitor Linux kernel updates for future security patches and verify patch application to ensure system security.

Why it matters

The CVE-2026-53104 memory leak vulnerability in the Linux kernel's mt76 wifi module requires patch application and system monitoring to prevent potential memory leaks and system crashes.

• Memory leak vulnerability can lead to increased memory usage and potential system crashes
• Successful exploitation requires local access and low privileges
• Patch application is necessary to prevent potential memory leaks
• Verification of patch application and system monitoring are recommended

Technical summary

The Linux kernel's mt76 wifi module has a memory leak vulnerability when destroying device-related rx queues. The vulnerability has been resolved through a series of patches applied to the Linux kernel. Affected kernel versions include 6.8 to 6.18.33 and 6.19 to 7.0.10. The patches fix the issue by properly handling the destruction of rx queues and page_pool. Users should update to a patched version to prevent potential memory leaks and system crashes. The vulnerability requires local access and low privileges to exploit.

Defensive priority

Medium priority for Linux kernel maintainers and users, especially those using affected kernel versions.

Recommended defensive actions

• Review and apply patches for affected Linux kernel versions
• Update Linux kernel to version 6.18.33 or later, or 7.0.10 or later
• Monitor Linux kernel updates for future security patches
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
