Description OSIDB Bzimport 2026-09-17 17:25:43 UTC
In the Linux kernel, the following vulnerability has been resolved:

thermal: intel: int3400: clean up ODVP on probe failures

evaluate_odvp() creates per-ODVP sysfs files before the thermal zone
and later probe resources are registered. The current unwind path only
calls cleanup_odvp() from the late sysfs failure path, so failures after
evaluate_odvp() but before that label, including
thermal_tripless_zone_device_register() failures, leave the ODVP files
and storage behind.

Move the ODVP cleanup to the common ART/TRT unwind path so every failure
after evaluate_odvp() releases the ODVP state. Also clear the cached
ODVP pointers in cleanup_odvp(), because evaluate_odvp() can already call
it for partial setup failures while probe continues.
