  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  ublk_drv: fix NULL pointer dereference in ublk_c...",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  ublk_drv: fix NULL pointer dereference in ublk_ctrl_start_recovery()  When two UBLK_CMD_START_USER_RECOVERY commands are submitted, the first one sets \u0027ubq-\u003Eubq_daemon\u0027 to NULL, and the second one triggers WARN in ublk_queue_reinit() and subsequently a NULL pointer dereference issue.  Fix it by adding the check in ublk_ctrl_start_recovery() and return immediately in case of zero \u0027ub-\u003Enr_queues_ready\u0027.
