CVE-2026-43467

CVE-2026-43467 affects the Linux kernel mlx5_core/mlx5_eswitch stack. Root cause: when moving a device to switchdev mode on a system that does not support IPsec, the code erroneously cleans up IPsec resources, triggering a local crash/DoS. With concrete details from multiple vendors (Red Hat, SUS...

CVE-2026-43465

CVE-2026-43465: Linux kernel mlx5e XDP multi-buf frag counting flaw. When XDP programs modify the XDP buffer layout (via bpf_xdp_pull_data/bpf_xdp_adjust_tail), the driver failed to count dropped fragments, risking negative page fragment reference counting and potential instability. Public report...
