Fix the test by\nrequiring `it->options[1]` to be within bounds before proceeding with\nthe original test.  Valid `it->options[1]` values that select the IRQ\nwill be in the range [1,15]. The value 0 explicitly disables the use of\ninterrupts.","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:N/A:H","score":7.1},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/3eab654f5d199ecd45403c6588cda63e491fcfca","https://git.kernel.org/stable/c/4a3c18cde02e35aba87e0ad5672b3e1c72dda5a4","https://git.kernel.org/stable/c/70f2b28b5243df557f51c054c20058ae207baaac","https://git.kernel.org/stable/c/73f34d609397805c20d6b2ef5c07a4cbf7c4d63a","https://git.kernel.org/stable/c/8a3637027ceeba4ca5e500b23cb7d24c25592513"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-38482","score":0.00195,"percentile":0.09268,"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).
