About this tag
AF_ALG is a Linux kernel cryptographic API socket interface that allows user-space programs to access kernel crypto operations. The tag covers discussions of security vulnerabilities in this subsystem, such as CVE-2026-46033, where malformed authentication tag instances can lead to out-of-bounds access. While AF_ALG is a Linux feature, it is relevant to Windows users who run WSL, Linux VMs, containers, or cloud workloads. The content emphasizes that kernel crypto plumbing is an important attack surface for administrators to monitor, similar to networking or filesystem code. The tag provides guidance on patching and understanding risks associated with AF_ALG in mixed environments.
