Apply the equivalent fix here: widen the port accumulator\nto u32 and reject values above 65535, and reject address octets above\n255.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","score":7.3},"cwes":[],"references":["https://git.kernel.org/stable/c/00bcc6d679262ea42688fba1d7819ea6e56f12ef","https://git.kernel.org/stable/c/4aed450adaee3a021db27be94c61fe025b0d05ff","https://git.kernel.org/stable/c/50cb9b7263a2ed01f7d2f97818a800c2ee05f661","https://git.kernel.org/stable/c/b1908bff0faaa94d55be72da65879cad632e8236","https://git.kernel.org/stable/c/d02de9a7a7e2484da0cf37e50614840623b98a62"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90141","score":0.00445,"percentile":0.38412,"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).
