# CVE-2026-53016

> 7.8 HIGH

## Beschreibung

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.
