Description OSIDB Bzimport 2026-07-19 15:02:08 UTC 
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.
