kernel: crypto: seqiv - Do not use req->iv after crypto_aead_encrypt

A use-after-free vulnerability was found in the Linux kernel's seqiv Sequence IV crypto module. After calling cryptoaeadencrypt, the underlying request may be freed by asynchronous completion handlers. The code then incorrectly dereferences req-iv to compare against info, accessing potentially...

CVE-2026-64439

A flaw was found in the Linux kernel's Kerberos 5 krb5 cryptography module.
