CVE-2026-53016

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.
