Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> freezer,umh: Fix call_usermode_helper_exec() vs SIGKILL<br /> <br /> Tetsuo-San noted that commit f5d39b020809 ("freezer,sched: Rewrite<br /> core freezer logic") broke call_usermodehelper_exec() for the KILLABLE<br /> case.<br /> <br /> Specifically it was missed that the second, unconditional,<br /> wait_for_completion() was not optional and ensures the on-stack<br /> completion is unused before going out-of-scope.
