{"apiVersion":"1.0","identifier":"CVE-2026-72467","description":"In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Check frwr_wp_create() during connect frwr_wp_create() creates the singleton Memory Region used to encode padding for Write chunks whose payload length is not XDR-aligned. Its failure paths return a negative errno and leave ep->re_write_pad_mr set to NULL. rpcrdma_xprt_connect() currently ignores that return value. If frwr_wp_create() fails after the rest of the connection setup succeeds, xprt_rdma_connect_worker() treats the connection attempt as successful and sets XPRT_CONNECTED. A later NFS/RDMA read with a non-4-byte-aligned receive page length reaches rpcrdma_encode_write_list(), passes the NULL write-pad MR to encode_rdma_segment(), and dereferences it. This is locally triggerable on an NFS/RDMA client after a connect or reconnect hits a local MR allocation, DMA-map, MR-map, or post-send failure; a remote peer alone cannot force the local MR setup failure. Check the return value and fail the connect as -ENOTCONN, matching the adjacent setup failures. This keeps XPRT_CONNECTED clear and lets the normal reconnect path retry.","publishedAt":"2026-08-15T06:22:20","lastModifiedAt":"2026-08-17T06:19:14","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72467","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00206,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72467","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72467","en":"https://www.redsauce.net/en/cves/CVE-2026-72467","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72467","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72467","de":"https://www.redsauce.net/de/cves/CVE-2026-72467","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72467","el":"https://www.redsauce.net/el/cves/CVE-2026-72467"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72467"}}
