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()).","state":0,"publishedAt":"2026-08-15T05:53:05.874+00:00","modifiedAt":"2026-10-16T18:44:58.318+00:00","affected":[{"ecosystem":"Vendor
