CVE-2026-53016

crypto: ccp - copy IV using skcipher ivsize

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.

CWE-787 Out-of-bounds Write

The product writes data past the end, or before the beginning, of the intended buffer.

CWE-805 Buffer Access with Incorrect Length Value

The product uses a sequential operation to read or write a buffer, but it uses an incorrect length value that causes it to access memory that is outside of the bounds of the buffer.
