  "description": "In the Linux kernel, the following vulnerability has been resolved:  s390/cio: fix race condition during online processing  A race condition exists in ccw_device_set_online() that can cause the online process to fail, leaving the affected device in an inconsistent state. As a result, subsequent attempts to set that device online fail with return code ENODEV.  The problem occurs when a path verification request arrives after a wait for final device state completed, but before the result state is evaluated.  Fix this by ensuring that the CCW-device lock is held between determining final state and checking result state.  Note that since:  commit 2297791c92d0 (\u0022s390/cio: dont unregister subchannel from child-drivers\u0022)  path verification requests are much more likely to occur during boot, resulting in an increased chance of this race condition occurring.",
