{"cve":"CVE-2026-72467","nvd":{"published":"2026-08-15T06:22:20.770","modified":"2026-08-17T06:19:14.580","status":"Received","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nxprtrdma: Check frwr_wp_create() during connect\n\nfrwr_wp_create() creates the singleton Memory Region used to encode\npadding for Write chunks whose payload length is not XDR-aligned. Its\nfailure paths return a negative errno and leave ep->re_write_pad_mr set\nto NULL.\n\nrpcrdma_xprt_connect() currently ignores that return value. If\nfrwr_wp_create() fails after the rest of the connection setup succeeds,\nxprt_rdma_connect_worker() treats the connection attempt as successful\nand sets XPRT_CONNECTED. A later NFS/RDMA read with a non-4-byte-aligned\nreceive page length reaches rpcrdma_encode_write_list(), passes the NULL\nwrite-pad MR to encode_rdma_segment(), and dereferences it.\n\nThis is locally triggerable on an NFS/RDMA client after a connect or\nreconnect hits a local MR allocation, DMA-map, MR-map, or post-send\nfailure; a remote peer alone cannot force the local MR setup failure.\n\nCheck the return value and fail the connect as -ENOTCONN, matching the\nadjacent setup failures. This keeps XPRT_CONNECTED clear and lets the\nnormal reconnect path retry.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0f13fc7c7d2e0427517e63c739277a4cd338b0c5","https://git.kernel.org/stable/c/3b252fe1778b2cdd68283146455929801bc2abd7","https://git.kernel.org/stable/c/6b7be4f3feae322f1c2c40a3bdc99db93574a49e","https://git.kernel.org/stable/c/7471e66373a4444a57ef2192f8c4081202c54f45","https://git.kernel.org/stable/c/dd798b76a3481e392820c3ae86ed4592858c6b0f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72467","score":0.00215,"percentile":0.11866,"date":"2026-10-31"},"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).
