A USB device can trigger OOB by advertising the maximum\nnumber of properties.\n\nFix by dropping the redundant `+ i`; num_properties is already the correct\nrunning index, as gud_connector_fill_properties() fills the preceding\nslots.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2c92af27ad23e2fbc0367b11a9027d36d94ef4b3","https://git.kernel.org/stable/c/4153a9e008f2512bd3cf90a319436865847369b9","https://git.kernel.org/stable/c/59ced288fcba9e91bd38e61a972ad782c4edb7d0","https://git.kernel.org/stable/c/5f5e565410b4987e9663f599f9ab0c350f8338d4","https://git.kernel.org/stable/c/7e630edb22088df7aa0d55b02237a71e4c9a523d"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98181","score":0.00173,"percentile":0.0661,"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).
