The offsets are derived from firmware-provided strides,\nso the arithmetic can wrap before the bounds check, and the host wrapper\nsize is not the size of the firmware control interface being mapped.\n\nUse 64-bit arithmetic for the computed offsets and validate against the\nactual firmware control interface structure sizes with subtraction-based\nbounds checks. Also validate that the shared section is large enough for\nthe global control interface before using it.","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/33ae55809aee9b4dca1d00cdee35b527f2bf8626","https://git.kernel.org/stable/c/3e5c7cddc0073eef6f9bb373189b11a969f1f6f6","https://git.kernel.org/stable/c/6a47f9fd2d970674ed9dedc52fc7ab76fd015785","https://git.kernel.org/stable/c/80c9528661c774f899281c9a72011208ff39929e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-89825","score":0.00175,"percentile":0.06955,"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).
