ipsec offload

About this tag
The ipsec offload tag covers Linux kernel vulnerabilities and fixes related to IPsec hardware offload in high-speed networking drivers. Topics include a null-pointer dereference race in the bonding driver's IPsec offload path (CVE-2024-44990) and a scheduling-while-atomic bug in the Mellanox mlx5 Ethernet driver (CVE-2026-43199) triggered during IPsec MAC address handling. These issues highlight the complexity of combining cryptographic offload, kernel scheduling, and driver correctness. For WindowsForum readers, the content emphasizes understanding where Linux IPsec offload appears in mixed environments and the importance of patching such flaws even when they lack flashy exploit scenarios.

    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...
