CVE-2026-53016 is an out-of-bounds write vulnerability in the Linux kernel CCP cryptographic driver. AF_ALG requests using rfc3686-ctr-aes-ccp supply an 8-byte initialization vector, but ccp_aes_complete() restores AES_BLOCK_SIZE bytes, equivalent to 16 bytes, into the caller's IV buffer. This length mismatch writes eight bytes beyond the buffer boundary. The flaw can cause memory corruption and potentially denial of service.
