Title
hv_netvsc: Fix race condition between netvsc_probe and netvsc_remove
Summary
In the Linux kernel, the following vulnerability has been resolved: hv_netvsc: Fix race condition between netvsc_probe and netvsc_remove In commit ac5047671758 ("hv_netvsc: Disable NAPI before closing the VMBus channel"), napi_disable was getting called for all channels, including all subchannels without confirming if they are enabled or not. This caused hv_netvsc getting hung at napi_disable, when netvsc_probe() has finished running but nvdev->subchan_work has not started yet. netvsc_subchan_work() -> rndis_set_subchannel() has not created the sub-channels and because of that netvsc_sc_open() is not running. netvsc_remove() calls cancel_work_sync(&nvdev->subchan_work), for which netvsc_subchan_work did not run. netif_napi_add() sets the bit NAPI_STATE_SCHED because it ensures NAPI cannot be scheduled. Then netvsc_sc_open() -> napi_enable will clear the NAPIF_STATE_SCHED bit, so it can be scheduled. napi_disable() does the opposite. Now during netvsc_device_remove(), when napi_disable is called for those subchannels, napi_disable gets stuck on infinite msleep. This fix addresses this problem by ensuring that napi_disable() is not getting called for non-enabled NAPI struct. But netif_napi_del() is still necessary for these non-enabled NAPI struct for cleanup purpose.

confirming if they are enabled or not.\\n\\nThis caused hv_netvsc getting hung at napi_disable, when netvsc_probe()\\nhas finished running but nvdev-\u003esubchan_work has not started yet.\\nnetvsc_subchan_work() -\u003e rndis_set_subchannel() has not created the\\nsub-channels and because of that netvsc_sc_open() is not running.\\nnetvsc_remove() calls cancel_work_sync(\u0026nvdev-\u003esubchan_work), for which\\nnetvsc_subchan_work did not run.\\n\\nnetif_napi_add() sets the bit NAPI_STATE_SCHED because it ensures NAPI\\ncannot be scheduled. Then netvsc_sc_open() -\u003e napi_enable will clear the\\nNAPIF_STATE_SCHED bit, so it can be scheduled. napi_disable() does the\\nopposite.\\n\\nNow during netvsc_device_remove(), when napi_disable is called for those\\nsubchannels, napi_disable gets stuck on infinite msleep.\\n\\nThis fix addresses this problem by ensuring that napi_disable() is not\\ngetting called for non-enabled NAPI struct.\\nBut netif_napi_del() is still necessary for these non-enabled NAPI struct\\nfor cleanup purpose.\\n\\nCall trace:\\n[  654.559417] task:modprobe        state:D stack:    0 pid: 2321 ppid:  1091 flags:0x00004002\\n[  654.568030] Call Trace:\\n[  654.571221]  \u003cTASK\u003e\\n[  654.573790]  __schedule+0x2d6/0x960\\n[  654.577733]  schedule+0x69/0xf0\\n[  654.581214]  schedule_timeout+0x87/0x140\\n[  654.585463]  ? __bpf_trace_tick_stop+0x20/0x20\\n[  654.590291]  msleep+0x2d/0x40\\n[  654.593625]  napi_disable+0x2b/0x80\\n[  654.597437]  netvsc_device_remove+0x8a/0x1f0 [hv_netvsc]\\n[  654.603935]  rndis_filter_device_remove+0x194/0x1c0 [hv_netvsc]\\n[  654.611101]  ? do_wait_intr+0xb0/0xb0\\n[  654.615753]  netvsc_remove+0x7c/0x120 [hv_netvsc]\\n[  654.621675]  vmbus_remove+0x27/0x40 [hv_vmbus]\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.10.210\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.15.149\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.79\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.18\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.7.6\", \"versionStartIncluding\": \"5.8\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.8\", \"versionStartIncluding\": \"5.8\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-05-11T20:02:28.322Z\"}}}",
