      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Fix scheduling while atomic\n\nThe driver makes a call into midlayer (fc_remote_port_delete) which can put\nthe thread to sleep. The thread that originates the call is in interrupt\ncontext. The combination of the two trigger a crash. Schedule the call in\nnon-interrupt context where it is more safe.\n\nkernel: BUG: scheduling while atomic: swapper/7/0/0x00010000\nkernel: Call Trace:\nkernel:  <IRQ>\nkernel:  dump_stack+0x66/0x81\nkernel:  __schedule_bug.cold.90+0x5/0x1d\nkernel:  __schedule+0x7af/0x960\nkernel:  schedule+0x28/0x80\nkernel:  schedule_timeout+0x26d/0x3b0\nkernel:  wait_for_completion+0xb4/0x140\nkernel:  ? wake_up_q+0x70/0x70\nkernel:  __wait_rcu_gp+0x12c/0x160\nkernel:  ? sdev_evt_alloc+0xc0/0x180 [scsi_mod]\nkernel:  synchronize_sched+0x6c/0x80\nkernel:  ? call_rcu_bh+0x20/0x20\nkernel:  ? __bpf_trace_rcu_invoke_callback+0x10/0x10\nkernel:  sdev_evt_alloc+0xfd/0x180 [scsi_mod]\nkernel:  starget_for_each_device+0x85/0xb0 [scsi_mod]\nkernel:  ? scsi_init_io+0x360/0x3d0 [scsi_mod]\nkernel:  scsi_init_io+0x388/0x3d0 [scsi_mod]\nkernel:  device_for_each_child+0x54/0x90\nkernel:  fc_remote_port_delete+0x70/0xe0 [scsi_transport_fc]\nkernel:  qla2x00_schedule_rport_del+0x62/0xf0 [qla2xxx]\nkernel:  qla2x00_mark_device_lost+0x9c/0xd0 [qla2xxx]\nkernel:  qla24xx_handle_plogi_done_event+0x55f/0x570 [qla2xxx]\nkernel:  qla2x00_async_login_sp_done+0xd2/0x100 [qla2xxx]\nkernel:  qla24xx_logio_entry+0x13a/0x3c0 [qla2xxx]\nkernel:  qla24xx_process_response_queue+0x306/0x400 [qla2xxx]\nkernel:  qla24xx_msix_rsp_q+0x3f/0xb0 [qla2xxx]\nkernel:  __handle_irq_event_percpu+0x40/0x180\nkernel:  handle_irq_event_percpu+0x30/0x80\nkernel:  handle_irq_event+0x36/0x60",
