  "description": "In the Linux kernel, the following vulnerability has been resolved:  ping: Fix potentail NULL deref for /proc/net/icmp.  After commit dbca1596bbb0 (\u0022ping: convert to RCU lookups, get rid of rwlock\u0022), we use RCU for ping sockets, but we should use spinlock for /proc/net/icmp to avoid a potential NULL deref mentioned in the previous patch.  Let\u0027s go back to using spinlock there.  Note we can convert ping sockets to use hlist instead of hlist_nulls because we do not use SLAB_TYPESAFE_BY_RCU for ping sockets.",
