The bounds check admits any\noffset with off + len <= inline_data_size, but the mapping still assumes\nthe data begins in the first inline page:\n\n\tsg->offset = off;\n\tsg->length = min_t(int, len, PAGE_SIZE - off);\n\nWhen a port is configured with inline_data_size > PAGE_SIZE (settable up\nto max(SZ_16K, PAGE_SIZE)), an offset in (PAGE_SIZE, inline_data_size]\nmakes \"PAGE_SIZE - off\" underflow, so sg->length is set to ~4 GiB and\nthe block backend reads far past the first inline page.  num_pages(len)\nalso ignores the offset, so an in-bounds offset whose [off, off+len)\nspan crosses a page boundary under-counts the scatterlist.\n\nMap the offset properly: split it into a page index and an in-page\noffset, start the scatterlist at that page, and size the page count from\npage_off + len.  Because the request scatterlist may now start at\ninline_sg[page_idx] rather than inline_sg[0], generalize the inline-SGL\nidentity test in nvmet_rdma_release_rsp() to a range test; otherwise the\npersistent inline scatterlist is mistaken for an allocated one and\nnvmet_req_free_sgls() frees an inline page (and warns in\nfree_large_kmalloc()).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":[],"references":["https://git.kernel.org/stable/c/11401371152b228448a41d79c6de1c938f93049a","https://git.kernel.org/stable/c/2944113ad5fbcdf5d349d857c03d2a44b6de75b8","https://git.kernel.org/stable/c/42a8ea3acd883f4f210d9e54e0975b1e2292b529","https://git.kernel.org/stable/c/48c0162f647bb47e6084ffbc71b8f213f5e2f4f8","https://git.kernel.org/stable/c/7c96581169c9d9a7d0726e554313acfbead6141c"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72129","score":0.00714,"percentile":0.53396,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
