UAF follows.\n\nThe fix is two-fold:\n\n- Before dropping the irq and ap_list locks, take a reference on\n  the irq\n\n- Do not try to handle migration of the pending bit: there is no\n  expectation that this state is retained, as per the architecture\n\nWith that, we're sure that the interrupt is still around, and we\nsafely remove it from the AP list as it has no target at this\nstage (unless another interrupt fires, but that's another story).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":9.3},"cwes":[],"references":["https://git.kernel.org/stable/c/7258770e5814f15e8308ebda82ac9acf6964ba8e","https://git.kernel.org/stable/c/77c61235d66246dd6a5f55587f0afc273d832775","https://git.kernel.org/stable/c/b1a89d12d35a8256d2b170ced0b1c86851f3def2","https://git.kernel.org/stable/c/d19dca8194ebed371e624331c6be2cb73b562caf","https://git.kernel.org/stable/c/eb74f3feb68e64cf69f86cb806a15d8cfb6757f4"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-72288","score":0.00185,"percentile":0.08015,"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).
