CVE-2026-63839

Summary

In the Linux kernel, the following vulnerability has been resolved:

platform/x86: lenovo-wmi-helpers: Fix memory leak in lwmi_dev_evaluate_int()

lwmi_dev_evaluate_int() leaks output.pointer when retval == NULL (found by sashiko.dev [1]).

Fix it by moving ret_obj = output.pointer' outside of the if (retval)' block so that it is always freed by the __free cleanup callback.

No functional change intended.
