  "details": "In the Linux kernel, the following vulnerability has been resolved:  xen-netback: Fix XenBus connection failure cleanup  xenvif_get_stats and xenvif_get_ethtool_stats capture vif-\u003enum_queues under rcu_read_lock. We need to unpublish vif-\u003enum_queues before synchronize_net to ensure that readers that come afterwards will not read a non-zero vif-\u003enum_queues and attempt to access invalid queues.  This is the same cleanup algorithm as used in backend_disconnect and added in commit b17075d5c198 (\"xen-netback: fix race condition on XenBus disconnect\").  This is XSA-531",
