This can cause a lifetime issue if\nthe matched device is not the expected type, as by the time\nthe caller can introspect the object, it might be gone (the srcu\nlock having been dropped).\n\nGiven that there is only a single user of this helper, the simplest\noption is to move the locking responsibility to the caller, which\ncan keep the srcu lock held for as long as it wants.\n\nNote that this aligns with other kvm_io_bus*() helpers, which\nalready require the srcu lock to be held by the callers.","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/0cbae0e296d27ce4c4cce83e34d40c2bfd8133aa","https://git.kernel.org/stable/c/1b4a3c2f0509e7b0e65667f3c36676a849ee2755","https://git.kernel.org/stable/c/3a07249981629ace483ebbef81ef6b34c2d2afec","https://git.kernel.org/stable/c/7099e7148f81c605bbc319b16ce0131540341560","https://git.kernel.org/stable/c/90d35d2b8e47afd68fe2a4dd0eeb60bc71641775"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72282","score":0.00176,"percentile":0.07077,"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).
