However\nrpcrdma_ep_create() currently stores that pointer in ep->re_id only\nafter rpcrdma_create_id() returns.\n\nA local administrator can race an NFS/RDMA mount against RDMA device\nremoval. If rpcrdma_remove_one() observes the just-registered\nnotification before rpcrdma_ep_create() assigns ep->re_id,\nrpcrdma_ep_removal_done() calls trace_xprtrdma_device_removal(NULL).\nThe tracepoint dereferences id->device->name and copies\nid->route.addr.dst_addr, so the callback can crash the kernel with a\nNULL pointer dereference.\n\nStore the rdma_cm_id in ep->re_id immediately before publishing\nep->re_rn. The existing error path still destroys the id directly if\nregistration fails; ep is then freed by the caller without using\nep->re_id. Remove the later duplicate assignment in rpcrdma_ep_create().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/264ccd7871915749bee55fe0c39467a7f08d5479","https://git.kernel.org/stable/c/28743571c17b58c21a7216fc9faaf8028df5869b","https://git.kernel.org/stable/c/51248d877bbc6e604e38aeaf776c2781cb4f0dbd","https://git.kernel.org/stable/c/bb7caa63e1db22fd03e8dc591b12169e99169dff"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72468","score":0.00209,"percentile":0.11048,"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).
