"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/qeth: fix deadlock during failing recovery\n\nCommit 0b9902c1fcc5 (\"s390/qeth: fix deadlock during recovery\") removed\ntaking discipline_mutex inside qeth_do_reset(), fixing potential\ndeadlocks. An error path was missed though, that still takes\ndiscipline_mutex and thus has the original deadlock potential.\n\nIntermittent deadlocks were seen when a qeth channel path is configured\noffline, causing a race between qeth_do_reset and ccwgroup_remove.\nCall qeth_set_offline() directly in the qeth_do_reset() error case and\nthen a new variant of ccwgroup_set_offline(), without taking\ndiscipline_mutex."
