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...

CVE-2026-43464

Summary: CVE-2026-43464 affects the Linux kernel mlx5e driver in XDP multi-buffer scenarios. When XDP programs modify buffer layout via bpf_xdp_pull_data() or bpf_xdp_adjust_tail(), the driver previously failed to count dropped fragments, causing negative page reference counts during cleanup and ...
