If hinic3_tx_csum() falls back to\nskb_checksum_help() for unsupported tunnel packets, the skb may be\nlinearized. Continuing to build the TX descriptor with the stale\nfragment count leads to a descriptor mismatch, which can trigger\nout-of-bounds DMA reads or IOMMU faults.\n\nFurthermore, the old code ignored the return value of skb_checksum_help(),\ntransmitting corrupted packets with incomplete checksums upon failure.\n\nFix this by:\n1. Moving the hinic3_tx_offload() call before calculating 'num_sge' to\n   ensure the correct fragment count is used if the SKB is linearized.\n2. Propagating skb_checksum_help() errors and returning\n   HINIC3_TX_OFFLOAD_INVALID to properly drop the skb.","state":0,"publishedAt":"2026-09-17T16:06:41.055+00:00","modifiedAt":"2026-10-19T08:58:44.481+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/ethernet/huawei/hinic3/hinic3_tx.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"17fcb3dc12bbee8ec3e32ca1f60898f252e06b2d\",\n                            \"lessThan\": \"e794cdc5c369c1b06359e2fe03a8d9270f56bead\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"17fcb3dc12bbee8ec3e32ca1f60898f252e06b2d\",\n                            \"lessThan\": \"96c3959770386b2913c62005f0d0c3151e0c01c3\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"17fcb3dc12bbee8ec3e32ca1f60898f252e06b2d\",\n                            \"lessThan\": \"d0c2bed6927cbfa2cb51f240b4812bf6916bce0e\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/ethernet/huawei/hinic3/hinic3_tx.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.16\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.52\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.6\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/e794cdc5c369c1b06359e2fe03a8d9270f56bead","https://git.kernel.org/stable/c/96c3959770386b2913c62005f0d0c3151e0c01c3","https://git.kernel.org/stable/c/d0c2bed6927cbfa2cb51f240b4812bf6916bce0e"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-90145","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-90145","identifiers":["CVE-2026-90145"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
