Description

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