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.

FC is a non-routable fabric, so Adjacent is the highest defensible vector.\nAC:L - The adjacent peer controls when I/O and abort complete relative to the fixed abort timer, and can complete the original command while delaying the abort IOCB so the timeout path runs after the SRB is already done. No uncontrollable race or rare config is required once that sequence is driven.\nPR:N - Fabric/link and target response timing are processed in the host driver without Linux credentials or capabilities on the victim. The attacker needs no local account on the vulnerable host.\nUI:N - No victim user action is required; with normal I/O to the malicious target, timeout and abort handling run automatically in the driver.\nS:U - Impact stays in the host kernel authority (SRB double-completion / heap UAF and crash). This is not a VM escape, IOMMU bypass, or other cross-boundary scope change.\nC:H - Double-calling done() on an SRB already removed from outstanding_cmds and freed back to the SRB mempool is a use-after-free, which can be leveraged for arbitrary kernel memory disclosure.\nI:H - The same double-completion UAF of a mempool-backed SRB enables heap reuse and control-flow/integrity compromise, not merely a clean failure path.\nA:H - The reported crash and any UAF-driven oops/panic or hang make availability High; double scsi_done/kref_put paths reliably destabilize the host."
