AI-suggested
A fix is available for this vulnerability. Users should apply the official Linux kernel updates that include the patch for CVE-2026-92504 to ensure proper cleanup of ODVP state on probe failures. No additional mitigation steps are indicated by the vendor advisory.
Description
A vulnerability in the Linux kernel's thermal driver for Intel int3400 devices was resolved. The issue involved improper cleanup of ODVP (On-Demand Voltage and Power) sysfs files on probe failures, which could leave residual files and storage allocated. This occurred because cleanup was only triggered on certain failure paths, missing others such as failures in thermal_tripless_zone_device_register(). The fix moves ODVP cleanup to a common unwind path to ensure all failures release ODVP state and clears cached pointers to prevent partial setup issues.
