For asynchronous return values, the cleanup helper returns before any further dereference.\nI:N - The stale value cannot drive a store, arbitrary free, or control-flow target, so the vulnerable path provides no modification primitive.\nA:H - The flaw produced an observed slab-use-after-free crash in seqiv_aead_encrypt, which can cause a fatal KASAN report, oops, or kernel panic."
