          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr\n\nAlthough ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it\nstill means hlist_for_each_entry_rcu can return an item that got removed\nfrom the list. The memory itself of such item is not freed thanks to RCU\nbut nothing guarantees the actual content of the memory is sane.\n\nIn particular, the reference count can be zero. This can happen if\nipv6_del_addr is called in parallel. ipv6_del_addr removes the entry\nfrom inet6_addr_lst (hlist_del_init_rcu(\u0026ifp-\u003eaddr_lst)) and drops all\nreferences (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough\ntiming, this can happen:\n\n1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry.\n\n2. Then, the whole ipv6_del_addr is executed for the given entry. The\n   reference count drops to zero and kfree_rcu is scheduled.\n\n3. ipv6_get_ifaddr continues and tries to increments the reference count\n   (in6_ifa_hold).\n\n4. The rcu is unlocked and the entry is freed.\n\n5. The freed entry is returned.\n\nPrevent increasing of the reference count in such case.
