rtnetlink

The rtnetlink tag on WindowsForum.com covers discussions about the Linux kernel's rtnetlink socket interface, particularly in the context of security vulnerabilities that affect mixed Windows and Linux environments. Recent content highlights CVE-2026-46132, an information-disclosure flaw where rtnetlink can leak uninitialized kernel stack data during SR-IOV network interface queries. While not a Windows vulnerability, the bug is relevant to Windows IT teams because modern infrastructures often run Linux in WSL, Hyper-V, Azure, Kubernetes, and other virtualization stacks. The tag focuses on kernel memory hygiene, network interface management, and the practical implications of Linux kernel bugs for Windows-centric organizations.
