Title
nvmet-fc: avoid deadlock on delete association path
Summary
In the Linux kernel, the following vulnerability has been resolved: nvmet-fc: avoid deadlock on delete association path When deleting an association the shutdown path is deadlocking because we try to flush the nvmet_wq nested. Avoid this by deadlock by deferring the put work into its own work item.

This matches the treatment of other NVMe target transports (nvmet-tcp/nvmet-fc) as network-reachable, and is consistent with CVE-2025-40171 on the same code.\nAC:L - A remote peer controls both sides of the race \u2014 it repeatedly creates associations and issues Disconnect Association LSes (or drops connectivity, triggering `nvmet_fc_invalidate_host()`), driving `del_work` and the LS completion onto `nvmet_wq` at will while the targetport reference count is winding down. No memory grooming or attacker-independent condition is required, and the trigger can be retried indefinitely.\nPR:N - FC-NVMe Link Service handling (`nvmet_fc_handle_ls_rqst()` \u2192 `nvmet_fc_ls_create_association()`/`nvmet_fc_ls_disconnect()`) runs before any NVMe-level authentication \u2014 it is the connect handshake itself, so no credentials or privileges are needed to reach the vulnerable teardown path.\nUI:N - The deadlock is reached purely through LS traffic processed asynchronously on `nvmet_wq` plus normal target-port teardown; no action by a local user or administrator on the victim is required to trigger it.\nS:U - The deadlock is confined to the kernel\u0027s NVMe target subsystem and its workqueue; no security boundary (VM, IOMMU, sandbox) is crossed and no other security authority\u0027s resources are affected.\nC:N - The bug is a nested workqueue flush that hangs; there is no out-of-bounds read, no use-after-free, and no path by which memory contents are exposed to the attacker.\nI:N - No memory is corrupted and no data is modified \u2014 the fix merely defers an existing `kref_put()` into its own work item, so there is no write primitive or control-flow impact.\nA:H - `fcloop_targetport_delete()` calls `flush_work()` on the work item that is itself executing, deadlocking a `nvmet_wq` kworker permanently; this wedges the shared WQ_MEM_RECLAIM `nvmet_wq` used by all nvmet transports and blocks `nvmet_fc_unregister_targetport()`/`nvmet_fc_exit_module()` in `flush_workqueue()` forever, requiring a reboot."

This matches the treatment of other NVMe target transports (nvmet-tcp/nvmet-fc) as network-reachable, and is consistent with CVE-2025-40171 on the same code.\\nAC:L - A remote peer controls both sides of the race \\u2014 it repeatedly creates associations and issues Disconnect Association LSes (or drops connectivity, triggering `nvmet_fc_invalidate_host()`), driving `del_work` and the LS completion onto `nvmet_wq` at will while the targetport reference count is winding down. No memory grooming or attacker-independent condition is required, and the trigger can be retried indefinitely.\\nPR:N - FC-NVMe Link Service handling (`nvmet_fc_handle_ls_rqst()` \\u2192 `nvmet_fc_ls_create_association()`/`nvmet_fc_ls_disconnect()`) runs before any NVMe-level authentication \\u2014 it is the connect handshake itself, so no credentials or privileges are needed to reach the vulnerable teardown path.\\nUI:N - The deadlock is reached purely through LS traffic processed asynchronously on `nvmet_wq` plus normal target-port teardown; no action by a local user or administrator on the victim is required to trigger it.\\nS:U - The deadlock is confined to the kernel\u0027s NVMe target subsystem and its workqueue; no security boundary (VM, IOMMU, sandbox) is crossed and no other security authority\u0027s resources are affected.\\nC:N - The bug is a nested workqueue flush that hangs; there is no out-of-bounds read, no use-after-free, and no path by which memory contents are exposed to the attacker.\\nI:N - No memory is corrupted and no data is modified \\u2014 the fix merely defers an existing `kref_put()` into its own work item, so there is no write primitive or control-flow impact.\\nA:H - `fcloop_targetport_delete()` calls `flush_work()` on the work item that is itself executing, deadlocking a `nvmet_wq` kworker permanently; this wedges the shared WQ_MEM_RECLAIM `nvmet_wq` used by all nvmet transports and blocks `nvmet_fc_unregister_targetport()`/`nvmet_fc_exit_module()` in `flush_workqueue()` forever, requiring a reboot.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"a07b4970f464f13640e28e16dad6cfa33647cc99\", \"lessThan\": \"5e0bc09a52b6169ce90f7ac6e195791adb16cec4\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"a07b4970f464f13640e28e16dad6cfa33647cc99\", \"lessThan\": \"9e6987f8937a7bd7516aa52f25cb7e12c0c92ee8\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"a07b4970f464f13640e28e16dad6cfa33647cc99\", \"lessThan\": \"eaf0971fdabf2a93c1429dc6bedf3bbe85dffa30\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"a07b4970f464f13640e28e16dad6cfa33647cc99\", \"lessThan\": \"1d86f79287206deec36d63b89c741cf542b6cadd\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"a07b4970f464f13640e28e16dad6cfa33647cc99\", \"lessThan\": \"710c69dbaccdac312e32931abcb8499c1525d397\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/nvme/target/fc.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.8\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.8\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.15.150\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.80\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.19\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.7.7\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.7.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/nvme/target/fc.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/5e0bc09a52b6169ce90f7ac6e195791adb16cec4\"}, {\"url\": \"https://git.kernel.org/stable/c/9e6987f8937a7bd7516aa52f25cb7e12c0c92ee8\"}, {\"url\": \"https://git.kernel.org/stable/c/eaf0971fdabf2a93c1429dc6bedf3bbe85dffa30\"}, {\"url\": \"https://git.kernel.org/stable/c/1d86f79287206deec36d63b89c741cf542b6cadd\"}, {\"url\": \"https://git.kernel.org/stable/c/710c69dbaccdac312e32931abcb8499c1525d397\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nnvmet-fc: avoid deadlock on delete association path\\n\\nWhen deleting an association the shutdown path is deadlocking because we\\ntry to flush the nvmet_wq nested.
