CVE-2026-92504 Linux CVE debrief

Who should care

Defenders and system administrators responsible for Linux kernel-based systems, particularly those utilizing the thermal: intel: int3400 component, should assess exposure and prioritize patching and verification efforts.

Why it matters

CVE-2026-92504 is a high-severity vulnerability in the Linux kernel that requires verification and patching to prevent potential attacks. Defenders and system administrators responsible for Linux kernel-based systems should assess exposure and prioritize patching efforts.

• Verification of patch application and system configuration is necessary to prevent potential high-severity attacks.
• Defenders should assess exposure and prioritize patching efforts for systems utilizing the affected Linux kernel components.
• Improper cleanup of ODVP files and storage on probe failures could lead to unnecessary resource utilization or potential security risks.

Technical summary

The vulnerability arises from the thermal: intel: int3400 component in the Linux kernel. The evaluate_odvp() function creates per-ODVP sysfs files before the thermal zone and later probe resources are registered. However, in case of probe failures after evaluate_odvp(), the current unwind path does not properly clean up the ODVP files and storage, potentially leaving behind unnecessary resources. This could lead to improper resource utilization or potential security risks if not properly addressed. Defenders should prioritize verifying and applying patches for this vulnerability, particularly for systems utilizing the affected Linux kernel components.

Defensive priority

Defenders should prioritize verifying and applying patches for this vulnerability, particularly for systems utilizing the affected Linux kernel components.

Recommended defensive actions

• Verify and apply patches for this vulnerability, particularly for systems utilizing the affected Linux kernel components.
• Review system configurations and ensure that the thermal: intel: int3400 component is properly configured and secured.
• Monitor system logs for potential exploitation attempts or anomalies related to this vulnerability.
• Perform a thorough review of system configurations and ensure that all necessary security measures are in place.
• Check for any unusual activity in system logs that may indicate exploitation attempts.
• Review and update asset inventory to ensure all affected systems are accounted for.
• Implement compensating controls for exposed systems while remediation is scheduled and verified.
