A second attach would then request the GPIO\nagain without having released it.\n\nSwitch back to a non-managed gpiod_get_optional() and keep the explicit\ngpiod_put() on the request_irq() error path and in\nsamsung_dsim_unregister_te_irq().\n\n[Luca: remove unnecessary comment]","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/5759bbef951c39d264ac0f47daa4137d01403aea","https://git.kernel.org/stable/c/77a43e00c57486a5212ef22d4665cafad62a5d4b","https://git.kernel.org/stable/c/9b796251c3cca45a33a5c859c6818c58aa982277","https://git.kernel.org/stable/c/ada667890773e033d2f40dc94176e3beb930b516","https://git.kernel.org/stable/c/ebffd70e4877bb7554974cf975a27872f2bb225f"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98605","score":0.00168,"percentile":0.06044,"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).
