In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: publish GC-visible tuple last nfflowtableiterate() only treats original-direction tuple nodes as owning entries. Publishing the original node first lets GC observe and free a flow while flowoffloadadd() is still inserting the reply node. Publish the reply node first and the original node last so GC never sees a partially installed flow. KASAN can trigger slab-use-after-free read and write reports in the flowtable/rhashtable path (rhtdeferredworker, jhash, flowoffloaddel, flowoffload_lookup, etc.).
