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 ...

CVE-2026-43031

The CVE concerns the Linux kernel xilinx axienet driver. When a TX packet spans multiple buffer descriptors, the current accounting in axienet_free_tx_chain summing per-BD lengths into an accumulator can lose earlier bytes if the packet completes across different polls, causing BQL to overestimat...

CVE-2025-68770

CVE-2025-68770 affects the bnxt_en driver in the Linux kernel. The issue occurs in the XDP_TX path: in bnxt_rx_xdp(), the event flags can be cleared too early when the XDP_TX action is taken again, potentially while the TX ring has no room. This can cause the TX producer to advance without the dr...
