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]","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98605","source_modified_at":"2026-10-19T09:22:32.426Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"e7447128ca4a250374d6721ee98e3e3cf99551a6","lessThan":"77a43e00c57486a5212ef22d4665cafad62a5d4b","status":"affected","versionType":"git"},{"version":"e7447128ca4a250374d6721ee98e3e3cf99551a6","lessThan":"5759bbef951c39d264ac0f47daa4137d01403aea","status":"affected","versionType":"git"},{"version":"e7447128ca4a250374d6721ee98e3e3cf99551a6","lessThan":"ebffd70e4877bb7554974cf975a27872f2bb225f","status":"affected","versionType":"git"},{"version":"e7447128ca4a250374d6721ee98e3e3cf99551a6","lessThan":"9b796251c3cca45a33a5c859c6818c58aa982277","status":"affected","versionType":"git"},{"version":"e7447128ca4a250374d6721ee98e3e3cf99551a6","lessThan":"ada667890773e033d2f40dc94176e3beb930b516","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98605","source_modified_at":"2026-10-19T09:22:32.426Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.4","status":"affected"},{"version":"0","lessThan":"6.4","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.55","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.9","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98605","source_modified_at":"2026-10-19T09:22:32.426Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"77a43e00c57486a5212ef22d4665cafad62a5d4b","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98605","source_modified_at":"2026-10-19T09:22:32.426Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"5759bbef951c39d264ac0f47daa4137d01403aea","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98605","source_modified_at":"2026-10-19T09:22:32.426Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"9b796251c3cca45a33a5c859c6818c58aa982277","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05718,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:19:18.294Z","modified_at":"2026-10-19T09:22:32.426Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98605","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:22:32.426Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98605","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/77a43e00c57486a5212ef22d4665cafad62a5d4b"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/5759bbef951c39d264ac0f47daa4137d01403aea"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ebffd70e4877bb7554974cf975a27872f2bb225f"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/9b796251c3cca45a33a5c859c6818c58aa982277"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ada667890773e033d2f40dc94176e3beb930b516"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:22:32.426Z","content_hash":"7726a57542a23133448e7ea7ecb95cc031e920bf24e3e8d0d09bd0fd23e0848f"}}
