z_vrfy_hwinfo_get_reset_cause() and z_vrfy_hwinfo_get_supported_reset_cause() pass an uninitialized stack variable to the implementation and then copy it to the user buffer whatever the implementation returned. In those cases memory from kernel stack are copied to user memory. Signed-off-by: Flavio Ceolin <flavio@hubble.com> (cherry picked from commit b98e1c7)
