NETDEV WATCHDOG: eno1np0 (bnxt_en): transmit queue 0 timed out\nThe fault address (0xfc499000) is on an exact 4KB page boundary,pointing to a DMA read buffer overrun.\nIn bnxt_start_xmit(), packets smaller than BNXT_MIN_PKT_SIZE (52 bytes),such as 42-byte untagged ARP frames, are padded:\n    if (length < BNXT_MIN_PKT_SIZE) {        pad = BNXT_MIN_PKT_SIZE - length;        if (skb_pad(skb, pad))            goto tx_kick_pending;        length = BNXT_MIN_PKT_SIZE;    }\n    mapping = dma_map_single(&pdev->dev, skb->data, len, DMA_TO_DEVICE);    ...    dma_unmap_len_set(tx_buf, len, len);\nHowever, 'len' was initialized earlier to skb_headlen(skb) (e.g. 42 bytes)and is left unadjusted after padding. Consequently, dma_map_single() anddma_unmap_len_set() map and track only 42 bytes.\nLater, the hardware TX buffer descriptor is programmed with the padded length:\n    txbd->tx_bd_len_flags_type =        cpu_to_le32(((len + pad) << TX_BD_LEN_SHIFT) | flags |                    TX_BD_FLAGS_PACKET_END);\nThe NIC DMA engine is thus instructed to read 52 bytes from a region whereonly 42 bytes were DMA-mapped. If skb->data ends near the boundary of a 4KBpage (within 'pad' bytes of the next page), the hardware DMA read overrunsinto the unmapped adjacent page, triggering an IOMMU fault.\nThis issue was exposed after commit 447cbe95ebb9 (\"vlan: fix skb_under_panicand races when toggling HW VLAN offload\") because reserving extra VLANheadroom rounded LL_RESERVED_SPACE from 48 up to 64 bytes, shifting skb->dataoffsets and potentially causing small frames to land right against pageboundaries.\nFix this by using skb_put_padto(skb, BNXT_MIN_PKT_SIZE) inbnxt_start_xmit(), before skb_shinfo(skb)->nr_frags is sampled,because padding might linearize the skb.This ensures skb->len and skb_headlen(skb) reflect the padded size sothat dma_map_single() maps the full buffer and the descriptor length isconsistent. This also removes the temporary 'pad' variable and masking logic.\nThe padding is done after the SW USO branch, otherwisebnxt_sw_udp_gso_xmit() would account the padding as UDP payloadand send it in extra segments.\nNote that SW USO segments are still not padded: with IPv4, a segmentcarrying less than 10 bytes of UDP payload (small gso_size, or a shortlast segment) is sent as a frame shorter than BNXT_MIN_PKT_SIZE.This is a separate issue, left for a followup patch.\nhttps://www.cve.org/CVERecord?id=CVE-2026-99081https://git.kernel.org/stable/c/cf8530a25ae92c4493e2f22981ecb46f0b66f4c8https://git.kernel.org/stable/c/2956aca14dd2977cd08bd2ccafae3beb8b84b268https://git.kernel.org/stable/c/fbd977e513971ccb4f0762a7f59eac500e474f89https://git.kernel.org/stable/c/5213f65a9667d3dd85db2e6df8f2e0516290db34https://git.kernel.org/stable/c/a51d233ccd4889aadb71dace863525cc2b00271e#kernel
