In the Linux kernel, the following vulnerability has been resolved:

crypto: ccp - copy IV using skcipher ivsize

AF ALG rfc3686-ctr-aes-ccp requests pass an 8-byte IV to the driver.

ccp aes complete() restores AES BLOCK SIZE bytes into the caller's IV buffer while RFC3686 skciphers expose an 8-byte IV, so the restore overruns the provided buffer.

Use crypto skcipher ivsize() to copy only the algorithm's IV length.
