Title
crypto: seqiv - Do not use req->iv after crypto_aead_encrypt
Summary
In the Linux kernel, the following vulnerability has been resolved: crypto: seqiv - Do not use req->iv after crypto_aead_encrypt As soon as crypto_aead_encrypt is called, the underlying request may be freed by an asynchronous completion. Thus dereferencing req->iv after it returns is invalid. Instead of checking req->iv against info, create a new variable unaligned_info and use it for that purpose instead.
Severity

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."
