network bonding

About this tag
Network bonding is a method of combining multiple network interfaces into a single logical link to increase throughput or provide failover. While primarily a Linux kernel feature, it is relevant to Windows users in hybrid environments where Linux networking runs inside WSL, containers, or cloud appliances managed from Windows. Recent discussions on WindowsForum cover Linux bonding driver vulnerabilities such as CVE-2026-43456 (type confusion when enslaving non-Ethernet devices like GRE tunnels) and CVE-2026-31419 (use-after-free in the broadcast transmit path). These bugs highlight the importance of understanding bonding configuration and kernel updates, especially for IT professionals managing mixed estates. The tag network bonding appears in threads about security risks, kernel fixes, and operational best practices for bonded interfaces.

  1. CVE-2026-43456: Linux Bonding Type Confusion via GRE — Hybrid Windows Risk Guide

    CVE-2026-43456 is a Linux kernel bonding-driver vulnerability published by NVD on May 8, 2026 and modified on May 11, in which a local privileged user can trigger type confusion when a non-Ethernet device such as a GRE tunnel is enslaved to a bond. The bug is not a Windows vulnerability in the...

  2. CVE-2026-31419 Bonding Use-After-Free: Fix with READ_ONCE Snapshot Count

    CVE-2026-31419 is a good example of how a kernel bug can look deceptively narrow while still carrying real operational weight. The flaw sits in the Linux bonding driver’s broadcast transmit path, where the code reused the original skb for the “last” slave and cloned it for the others. Under...
