    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: ccp - copy IV using skcipher ivsize\n\nAF_ALG rfc3686-ctr-aes-ccp requests pass an 8-byte IV to the driver.\n\nccp_aes_complete() restores AES_BLOCK_SIZE bytes into the caller's IV\nbuffer while RFC3686 skciphers expose an 8-byte IV, so the restore\noverruns the provided buffer.\n\nUse crypto_skcipher_ivsize() to copy only the algorithm's IV length.",
