Traffic interruption via incorrect XDP DMA offset
Published Apr 29, 2025 · Updated Aug 5, 2026
Packet corruption in the Linux kernel vmxnet3 driver allows local users to interrupt traffic through a native XDP program. vmxnet3_xdp_xmit_frame uses a fixed VMXNET3_XDP_HEADROOM instead of the XDP-adjusted data offset when calculating the DMA address. Reaching the flaw requires control of a native XDP program that moves xdp->data, adds an encapsulation header, and transmits on the same vmxnet3 interface; the malformed packet is dropped in transit.
