CVE-2026-53037 Linux CVE debrief

Who should care

Linux kernel maintainers, Linux distribution vendors, and organizations using Linux-based systems with HID devices should be aware of this vulnerability. These stakeholders need to assess the potential impact on their systems and apply necessary patches or mitigations. The vulnerability's resolution highlights the importance of coordinating device resets for components like HID and storage/UAS to avoid deadlocks.

Technical summary

The Linux kernel's HID component had a vulnerability (CVE-2026-53037) that could cause a deadlock when resetting a USB device with both HID and storage or UAS components. This was due to memory allocations in hid_pre_reset() and hid_post_reset() that could block on the mutex held during device reset. The fix applies GFP_NOIO to these allocations to prevent deadlocks. Linux kernel maintainers, distribution vendors, and users of Linux-based systems with HID devices should review and apply patches. The vulnerability emphasizes the need for careful handling of device resets in Linux kernel components.

Defensive priority

Medium

Recommended defensive actions

• Review and apply the kernel patches for HID component updates.
• Inventory Linux systems with HID devices for potential exposure.
• Monitor for any signs of device reset issues related to HID components.
• Verify the integrity of HID devices and their interactions with Linux kernel components.
• Assess the vulnerability's impact on Linux-based systems and prioritize patching based on risk.
• Implement compensating controls for exposed systems while remediation is scheduled and verified.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
