  2. Vulnerabilities (CVE)
  3. CVE-2022-49156
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

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: qla2xxx: Fix scheduling while atomic El controlador realiza una llamada a la capa intermedia (fc_remote_port_delete) que puede poner el hilo en suspensión. El hilo que origina la llamada está en un contexto de interrupción. La combinación de los dos desencadena un bloqueo. Programe la llamada en un contexto sin interrupciones donde sea más seguro. núcleo: ERROR: programación mientras atómico: swapper/7/0/0x00010000 núcleo: Seguimiento de llamadas: núcleo: 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
