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

ACPICA: Fix error code path in acpi_ds_call_control_method()

A use-after-free in acpi_ps_parse_aml() after a failing invocaion of

acpi_ds_call_control_method() is reported by KASAN [1] and code

inspection reveals that next_walk_state pushed to the thread by

acpi_ds_create_walk_state() is freed on errors, but it is not popped

from the thread beforehand. Thus acpi_ds_get_current_walk_state()

called by acpi_ps_parse_aml() subsequently returns it as the new

walk state which is incorrect.

To address this, make acpi_ds_call_control_method() call

acpi_ds_pop_walk_state() to pop next_walk_state from the thread before

returning an error.
