To avoid disturbing all the\nhappy paths, add an rdma_restrack_sync() operation which is sort of like\nflush_workqueue() or synchronize_irq(): after it returns, all the old\nnldev touches to the mr are gone and everything sees the new PD. This\nmakes it safe to reach into the PD pointer.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/05e26f34597e9c38bb5b340d86b179b23673869f","https://git.kernel.org/stable/c/1a132ee4e655288d9a0937ea5109a0d038431ae9","https://git.kernel.org/stable/c/50d5c02ab8e62325548bd3a6e6b758a9dcd6e7c3","https://git.kernel.org/stable/c/7a0cbb5721a1da81e902d73b6049f85ca8f3fc0a","https://git.kernel.org/stable/c/845c6b355226195dad1f26b300c4830f57034e8b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-74334","score":0.00129,"percentile":0.02542,"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).
