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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":39.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":207145,"id":"CVE-2026-90145","ts":1789757335784,"field":"cvss","old":null,"new":"7.1"},{"seq":207144,"id":"CVE-2026-90145","ts":1789757335784,"field":"severity","old":"none","new":"high"}]}
