Descriptions

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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: freezer,umh: Fix call_usermode_helper_exec() vs SIGKILL .Tetsuo-San notó que la confirmación f5d39b020809 ("freezer,sched: Rewrite core freezer logic") rompió call_usermodehelper_exec() para el caso KILLABLE. Específicamente, se pasó por alto que el segundo wait_for_completion() incondicional no era opcional y garantiza que la finalización en la pila no se utilice antes de salir del alcance.
