  "description": "In the Linux kernel, the following vulnerability has been resolved:  s390/dasd: fix Oops in dasd_alias_get_start_dev due to missing pavgroup  Fix Oops in dasd_alias_get_start_dev() function caused by the pavgroup pointer being NULL.  The pavgroup pointer is checked on the entrance of the function but without the lcu-\u003Elock being held. Therefore there is a race window between dasd_alias_get_start_dev() and _lcu_update() which sets pavgroup to NULL with the lcu-\u003Elock held.  Fix by checking the pavgroup pointer with lcu-\u003Elock held.",
