"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnvme-fc: release admin tagset if init fails\n\nnvme_fabrics creates an NVMe/FC controller in following path:\n\n nvmf_dev_write()\n -> nvmf_create_ctrl()\n -> nvme_fc_create_ctrl()\n -> nvme_fc_init_ctrl()\n\nnvme_fc_init_ctrl() allocates the admin blk-mq resources right after\nnvme_add_ctrl() succeeds. If any of the subsequent steps fail (changing\nthe controller state, scheduling connect work, etc.), we jump to the\nfail_ctrl path, which tears down the controller references but never\nfrees the admin queue/tag set. The leaked blk-mq allocations match the\nkmemleak report seen during blktests nvme/fc.\n\nCheck ctrl->ctrl.admin_tagset in the fail_ctrl path and call\nnvme_remove_admin_tag_set() when it is set so that all admin queue\nallocations are reclaimed whenever controller setup aborts."
