Description (CNA)
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.

ADP enrichment
A flaw was found in the Linux kernel's cryptographic coprocessor (CCP) driver. When processing AF_ALG rfc3686-ctr-aes-ccp requests, the ccp_aes_complete() function attempts to restore more data than the allocated buffer for the Initialization Vector (IV) can hold. This leads to a buffer overrun, which can result in memory corruption within the kernel.
