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.
En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: crypto: seqiv - No usar req->iv después de crypto_aead_encrypt Tan pronto como se llama a crypto_aead_encrypt, la solicitud subyacente puede ser liberada por una finalización asíncrona. Por lo tanto, desreferenciar req->iv después de que regresa es inválido. En lugar de comprobar req->iv contra info, crear una nueva variable unaligned_info y usarla para ese propósito en su lugar.
