{"id":"CVE-2026-90145","summary":"hinic3: Fix skb linearization mismatch and drop skb when skb_checksum_help() failed","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nhinic3: Fix skb linearization mismatch and drop skb when skb_checksum_help() failed\n\nPreviously, hinic3_send_one_skb() cached the skb fragment count before\ncalling hinic3_tx_offload(). 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.","modified":"2026-09-18T03:48:35.630279Z","published":"2026-09-17T16:06:41.055Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90145.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/96c3959770386b2913c62005f0d0c3151e0c01c3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d0c2bed6927cbfa2cb51f240b4812bf6916bce0e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e794cdc5c369c1b06359e2fe03a8d9270f56bead"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90145.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90145"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"17fcb3dc12bbee8ec3e32ca1f60898f252e06b2d"},{"fixed":"e794cdc5c369c1b06359e2fe03a8d9270f56bead"},{"fixed":"96c3959770386b2913c62005f0d0c3151e0c01c3"},{"fixed":"d0c2bed6927cbfa2cb51f240b4812bf6916bce0e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90145.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90145.json"}}],"schema_version":"1.9.0"}
