bridge mrp

About this tag
The bridge MRP (Media Redundancy Protocol) tag on WindowsForum.com covers discussions about the Linux kernel's bridge MRP implementation, particularly security vulnerabilities and stability issues. A notable topic is CVE-2026-31420, where a zero test interval supplied via netlink can cause the kernel to panic by exhausting memory through rapid MRP frame transmission. The fix involves rejecting zero values at the attribute-parsing layer to prevent invalid inputs from reaching workqueue logic. This tag is relevant for system administrators and developers working with network redundancy protocols and kernel security.

  1. CVE-2026-31420 Bridge MRP Zero Interval Can Panic Kernel

    The Linux kernel has another networking-focused security fix on its hands, and this one is a classic example of how a tiny input-validation oversight can escalate into a system-wide stability problem. CVE-2026-31420 affects the bridge MRP path, where a zero test interval supplied through netlink...
