Stale num_sge is caused by skb_checksum_help() linearizing a locally built encapsulated skb with SKBFL_SHARED_FRAG (sendfile/splice into GRE/Geneve/IPIP); no received protocol message supplies that fragment layout.\nAC:L - An attacker can sendfile/splice a non-GSO CHECKSUM_PARTIAL frame onto a non-VXLAN tunnel so hinic3_tx_csum() takes the unsupported-tunnel branch (l4_proto != UDP or dest != 4789) and skb_checksum_help() linearizes shared frags, desynchronizing the cached nr_frags with no race.\nPR:L - sendfile/splice on ordinary sockets needs no capability. On a host whose egress is a Geneve/GRE/IPIP overlay over hinic3, that traffic is encapsulated in-kernel and reaches hinic3_xmit_frame as an unprivileged local user (including from a container), without init-namespace CAP_NET_ADMIN.\nUI:N - The attacker triggers hinic3_tx_csum() by transmitting their own splice'd skb; no other user must mount media, open a file, or change configuration.\nS:U - hinic3_prepare_sq_ctrl() programs a wrong BUFDESC_NUM so the NIC DMA-reads leftover SQ buf_descs in host kernel context; that is not a guest-to-host escape, and unmapped IOVAs fault rather than bypass IOMMU policy.\nC:H - After skb_checksum_help() drops nr_frags, hinic3_tx_map_skb() fills only the remaining fragments while hinic3_prepare_sq_ctrl() still advertises the cached num_sge, so the NIC DMA-reads uninitialized SQ buf_descs (stale addresses/lengths) and can emit that host memory on the wire.\nI:N - SQ buf_descs carry only address/length for DMA_TO_DEVICE. hinic3_tx_map_skb() walks the post-linearize nr_frags and does not write out of bounds in the WQE, so there is no kernel write or control-flow primitive.\nA:H - The same stale BUFDESC_NUM makes the device DMA from leftover or unmapped IOVAs, which the fix describes as out-of-bounds DMA reads and IOMMU faults, and can stall the send queue when hardware walks garbage descriptors."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/huawei/hinic3/hinic3_tx.c"], "versions": [{"version": "17fcb3dc12bbee8ec3e32ca1f60898f252e06b2d", "lessThan": "e794cdc5c369c1b06359e2fe03a8d9270f56bead", "status": "affected", "versionType": "git"}, {"version": "17fcb3dc12bbee8ec3e32ca1f60898f252e06b2d", "lessThan": "96c3959770386b2913c62005f0d0c3151e0c01c3", "status": "affected", "versionType": "git"}, {"version": "17fcb3dc12bbee8ec3e32ca1f60898f252e06b2d", "lessThan": "d0c2bed6927cbfa2cb51f240b4812bf6916bce0e", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/huawei/hinic3/hinic3_tx.c"], "versions": [{"version": "6.16", "status": "affected"}, {"version": "0", "lessThan": "6.16", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.52", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2.6", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.3", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.16", "versionEndExcluding": "6.18.52"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.16", "versionEndExcluding": "7.2.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.16", "versionEndExcluding": "7.3"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/e794cdc5c369c1b06359e2fe03a8d9270f56bead"}, {"url": "https://git.kernel.org/stable/c/96c3959770386b2913c62005f0d0c3151e0c01c3"}, {"url": "https://git.kernel.org/stable/c/d0c2bed6927cbfa2cb51f240b4812bf6916bce0e"}], "title": "hinic3: Fix skb linearization mismatch and drop skb when skb_checksum_help() failed", "x_generator": {"engine": "bippy-1.2.0"}}}}
