"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvmxnet3: Fix packet corruption in vmxnet3_xdp_xmit_frame\n\nAndrew and Nikolay reported connectivity issues with Cilium's service\nload-balancing in case of vmxnet3.\n\nIf a BPF program for native XDP adds an encapsulation header such as\nIPIP and transmits the packet out the same interface, then in case\nof vmxnet3 a corrupted packet is being sent and subsequently dropped\non the path.\n\nvmxnet3_xdp_xmit_frame() which is called e.g. via vmxnet3_run_xdp()\nthrough vmxnet3_xdp_xmit_back() calculates an incorrect DMA address:\n\n page = virt_to_page(xdpf->data);\n tbi->dma_addr = page_pool_get_dma_addr(page) +\n VMXNET3_XDP_HEADROOM;\n dma_sync_single_for_device(&adapter->pdev->dev,\n tbi->dma_addr, buf_size,\n DMA_TO_DEVICE);\n\nThe above assumes a fixed offset (VMXNET3_XDP_HEADROOM), but the XDP\nBPF program could have moved xdp->data. While the passed buf_size is\ncorrect (xdpf->len), the dma_addr needs to have a dynamic offset which\ncan be calculated as xdpf->data - (void *)xdpf, that is, xdp->data -\nxdp->data_hard_start."

"value": "AV:N - The vulnerable code is reached purely by receiving a network packet on a vmxnet3 interface that a native XDP program encapsulates and returns XDP_TX for; no local access is needed and the corrupted/leaky frame is emitted onto the network.\nAC:L - On a target running a native XDP program that adjusts the head and XDP_TXes (a standard Cilium-on-VMware deployment), every such packet deterministically hits the wrong DMA offset — there is no race, no memory-layout dependency, and no condition the attacker must win.\nPR:N - A remote, unauthenticated attacker only has to send packets to the interface; the XDP program attachment is normal operator configuration, not something the attacker must obtain privileges for.\nUI:N - No victim action is required — the bug fires automatically during NAPI receive processing of an attacker-supplied packet.\nS:U - The mis-computed DMA address stays within the same page-pool page owned by the driver, so the impact remains within the kernel's own security authority with no VM/IOMMU boundary crossing.\nC:H - Each transmitted frame appends up to ~216 bytes of page content beyond the received packet — remnants of other flows received on the same NIC or non-zeroed pages freshly taken from the buddy allocator — and an attacker can drive this at packet rate to harvest a large aggregate of kernel memory onto the wire.\nI:L - The frame placed on the wire is not what the BPF program constructed (the encap/rewritten header is dropped and attacker-controlled bytes land in header positions), which can defeat an XDP-based encapsulation or sanitization policy, but no kernel memory is written and there is no arbitrary-write primitive.\nA:L - The corrupted frames are dropped on the path, breaking connectivity for the affected XDP-forwarded traffic, but the DMA window provably stays inside the mapped page so there is no oops, hang, or panic."
