Hi Lukas, I will move the new declaration up below the one for child_req. Since out_buf is incremented later in the function rsassa_pkcs1_verify(), key_buf was introduced to preserve the original address returned by kmalloc(). I tried the following approach, but it would require replacing all existing occurrences of out_buf with ptr. u8 *out_buf __free(kfree_sensitive) = NULL; u8 *ptr; ptr = out_buf; Could you please give me some advice on this? Thanks a lot. Kind regards, Changwei
