This also matches switch_mode(), which\nonly updates fields it recognizes.\n\nFound with Clang's -Wconditional-uninitialized.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2d92c250815cba6bffd64f0125fac7afe4fa6ce0","https://git.kernel.org/stable/c/324cc98b71f0d3dee7367ef3c669fd80747e71b6","https://git.kernel.org/stable/c/3efb7f6491526f5012f9ec94769e9ed832feeef8"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90197","score":0.00206,"percentile":0.106,"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).
