      "title": "scsi: qla2xxx: Quiesce response IRQ before freeing request queue",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Quiesce response IRQ before freeing request queue\n\nqla2xxx_delete_qpair() deletes the request queue before the response\nqueue. qla25xx_delete_req_que() frees the request queue memory\n(kfree(req) in qla25xx_free_req_que()), but the response-queue MSI-X is\nonly released later, in qla25xx_free_rsp_que(). In that window the\nresponse interrupt can still fire, qla2xxx_msix_rsp_q() queues\nqpair->q_work, and qla_do_work() -> qla24xx_process_response_queue()\ndereferences the now-freed rsp->req (LOGINOUT/CT/ELS entries and the\nstatus path), a use-after-free.\n\nThe cancel_work_sync() added for the qpair teardown lives in the\nresponse free path, which runs after the request queue is already freed,\nso it does not protect rsp->req.\n\nRelease the response-queue interrupt and flush qpair->q_work before\ndeleting the request queue, so no late completion can reach the freed\nrequest queue. Clearing have_irq makes the subsequent\nqla25xx_free_rsp_que() skip its free_irq(), and the firmware\nqueue-delete order (request then response) is preserved; the\nrequest-delete mailbox completes on the default vector and is unaffected\nby dropping the qpair response interrupt early.",
