Title
scsi: qla2xxx: Fix crash when I/O abort times out
Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix crash when I/O abort times out While performing CPU hotplug, a crash with the following stack was seen: Call Trace: qla24xx_process_response_queue+0x42a/0x970 [qla2xxx] qla2x00_start_nvme_mq+0x3a2/0x4b0 [qla2xxx] qla_nvme_post_cmd+0x166/0x240 [qla2xxx] nvme_fc_start_fcp_op.part.0+0x119/0x2e0 [nvme_fc] blk_mq_dispatch_rq_list+0x17b/0x610 __blk_mq_sched_dispatch_requests+0xb0/0x140 blk_mq_sched_dispatch_requests+0x30/0x60 __blk_mq_run_hw_queue+0x35/0x90 __blk_mq_delay_run_hw_queue+0x161/0x180 blk_execute_rq+0xbe/0x160 __nvme_submit_sync_cmd+0x16f/0x220 [nvme_core] nvmf_connect_admin_queue+0x11a/0x170 [nvme_fabrics] nvme_fc_create_association.cold+0x50/0x3dc [nvme_fc] nvme_fc_connect_ctrl_work+0x19/0x30 [nvme_fc] process_one_work+0x1e8/0x3c0 On abort timeout, completion was called without checking if the I/O was already completed. Verify that I/O and abort request are indeed outstanding before attempting completion.
