af_alg rfc3686

The af_alg rfc3686 tag brings together coverage of a Linux kernel security issue involving AF_ALG RFC3686 CTR-AES operations and the AMD CCP cryptographic driver. CVE-2026-53016 concerns an AES completion path that may copy a 16-byte initialization vector into an 8-byte caller-provided buffer. The reported flaw is local rather than remote, but it affects kernel memory handling and illustrates why crypto acceleration code requires careful boundary checks. This archive is relevant for readers tracking Linux kernel vulnerabilities, cryptographic subsystems, buffer overruns, CVSS assessments, and the security implications of implementation errors in low-level operating-system infrastructure.
