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
(“s390/cio: dont unregister subchannel from child-drivers”) path
verification requests are much more likely to occur during boot, resulting
in an increased chance of this race condition occurring.
