"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nPCI/IOV: Fix race between SR-IOV enable/disable and hotplug\n\nCommit 05703271c3cd (\"PCI/IOV: Add PCI rescan-remove locking when\nenabling/disabling SR-IOV\") tried to fix a race between the VF removal\ninside sriov_del_vfs() and concurrent hot unplug by taking the PCI\nrescan/remove lock in sriov_del_vfs(). Similarly the PCI rescan/remove lock\nwas also taken in sriov_add_vfs() to protect addition of VFs.\n\nThis approach however causes deadlock on trying to remove PFs with SR-IOV\nenabled because PFs disable SR-IOV during removal and this removal happens\nunder the PCI rescan/remove lock. So the original fix had to be reverted.\n\nInstead of taking the PCI rescan/remove lock in sriov_add_vfs() and\nsriov_del_vfs(), fix the race that occurs with SR-IOV enable and disable vs\nhotplug higher up in the callchain by taking the lock in\nsriov_numvfs_store() before calling into the driver's sriov_configure()\ncallback."
