This may leak the kernel\nstack contents. Make gpio_desc_to_lineinfo() return int so that the\n-ENODEV returned on failure to acquire the guard can be propagated to\nthe callers.\n\nWhile not strictly necessary: move the memset() before trying to acquire\nthe SRCU read lock too for good measure.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1feb5d39b05afd902ed9fc902ec5b15be03a4bdb","https://git.kernel.org/stable/c/60a466f231905cd96ae6f0f3c44a710c97873dac","https://git.kernel.org/stable/c/8460ee5216ab9a38263b01dca4b0a27e083f70f3","https://git.kernel.org/stable/c/cf3d043582e106a0e57002bec8a6de8929ba3e1c"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98528","score":0.00209,"percentile":0.10984,"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).
