Vulnerability Details CVE-2023-52704
In the Linux kernel, the following vulnerability has been resolved:
freezer,umh: Fix call_usermode_helper_exec() vs SIGKILL
Tetsuo-San noted that commit f5d39b020809 ("freezer,sched: Rewrite
core freezer logic") broke call_usermodehelper_exec() for the KILLABLE
case.
Specifically it was missed that the second, unconditional,
wait_for_completion() was not optional and ensures the on-stack
completion is unused before going out-of-scope.
