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