With those fields left unset, garbage function pointers\nmay be stored and later invoked from typec_partner_link_device() when a USB\ndevice is linked to the port. Uninitialized pd_revision and usb_capability\nsimilarly leak stack data through partner sysfs.\n\nZero-initialize the descriptor so optional callbacks remain NULL and the\nremaining fields are zero.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98759","source_modified_at":"2026-10-19T09:25:12.754Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"82432bbfb9e83b7e81d04660fe129b99a29b2ac2","lessThan":"75dc6cb377efd2f4428b7f76d3a590a0bbc10399","status":"affected","versionType":"git"},{"version":"82432bbfb9e83b7e81d04660fe129b99a29b2ac2","lessThan":"5414144e202a32437e3eb436cd3f5f00d79ad86e","status":"affected","versionType":"git"},{"version":"82432bbfb9e83b7e81d04660fe129b99a29b2ac2","lessThan":"88c7e458af53ff781a3f1051708395892b325576","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98759","source_modified_at":"2026-10-19T09:25:12.754Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.18","status":"affected"},{"version":"0","lessThan":"6.18","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","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-2026-98759","source_modified_at":"2026-10-19T09:25:12.754Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"75dc6cb377efd2f4428b7f76d3a590a0bbc10399","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98759","source_modified_at":"2026-10-19T09:25:12.754Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"5414144e202a32437e3eb436cd3f5f00d79ad86e","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98759","source_modified_at":"2026-10-19T09:25:12.754Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"88c7e458af53ff781a3f1051708395892b325576","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00206,"percentile":0.10161,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:47:47.988Z","modified_at":"2026-10-19T09:25:12.754Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98759","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:25:12.754Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98759","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/75dc6cb377efd2f4428b7f76d3a590a0bbc10399"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/5414144e202a32437e3eb436cd3f5f00d79ad86e"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/88c7e458af53ff781a3f1051708395892b325576"}],"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":"2026-10-19T09:25:12.754Z","content_hash":"bcba33635e19daf0944f233584017ed5e306ec4cf4ae42107adebf9ded5dd377"}}
