bonding driver

About this tag
The Linux bonding driver provides link aggregation and failover by combining multiple physical network interfaces into a single logical device. Recent discussions on WindowsForum.com cover kernel security patches and bug fixes for this driver, including a null-pointer dereference in the IPsec offload path (CVE-2024-44990), a data race in slave timestamp fields fixed with READ_ONCE/WRITE_ONCE, and a denial-of-service flaw in the debugfs RLB hash display (CVE-2026-31546). These threads focus on upstream Linux kernel changes that improve stability and security for systems using bonding, particularly in enterprise and data center environments where link redundancy is critical.

    CVE-2026-31546 Linux Bonding debugfs RLB NULL Dereference DoS Fix

    CVE-2026-31546 is a medium-severity Linux kernel denial-of-service flaw, published by NVD on April 24, 2026 and modified on April 28, that lets a local privileged user crash affected systems through the bonding driver’s debugfs RLB hash display path. The bug is small enough to fit in a...

    Linux Bonding Driver Data Race Fixed with READ_ONCE WRITE_ONCE

    A small, surgical change landed in the Linux kernel this month after syzbot and KCSAN flagged a data‑race in the bonding driver: fields used to track the last‑received timestamps on bond slaves—most notably slave->last_rx and slave->target_last_arp_rx[]—were being read and written locklessly...

    Linux Bonding IPsec Offload CVE-2024-44990 Patch: Null Pointer Race Fixed

    A race in the Linux bonding driver's IPsec offload path was closed this year after maintainers fixed a null-pointer dereference in bond_ipsec_offload_ok that could let a local, low‑privilege user crash an affected host — the patch corrects the function’s return type and adds an explicit check...
