This means\nthey can execute scv instructions after AIL is disabled, which causes an\ninterrupt at an unexpected entry location that crashes the kernel.\n\nChange the kexec sequence to disable AIL after other CPUs have been\nbrought down.\n\nAs a refresher, the real-mode scv interrupt vector is 0x17000, and the\nfixed-location head code probably couldn't easily deal with implementing\nsuch high addresses so it was just decided not to support that interrupt\nat all.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","score":4.4},"cwes":[],"references":["https://git.kernel.org/stable/c/21a741eb75f80397e5f7d3739e24d7d75e619011","https://git.kernel.org/stable/c/8c6506616386ce37e59b2745fc481c6713fae4f3","https://git.kernel.org/stable/c/c550679d604798d9fed8a5b2bb5693448a25407c","https://git.kernel.org/stable/c/d10e3c39001e9194b9a1bfd6979bd3fa19dccdc5","https://git.kernel.org/stable/c/21a741eb75f80397e5f7d3739e24d7d75e619011"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:53:51.317825789+00:00"},"epss":{"cve":"CVE-2024-42230","score":0.00202,"percentile":0.10162,"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).
