Work that runs after\nucsi_unregister() has been called touches freed state: it dereferences\nthe connector array that ucsi_unregister() freed, or registers and\nunregisters the instance a second time.\n\nDisable both work items with disable_work_sync() before unregistering,\nand unregister only if the instance is still registered.\n\nThis issue was found by an in-house static analysis tool.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98758","source_modified_at":"2026-10-19T09:25:11.783Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"62b5412b1f4afab27d8df90ddcabb8e1e11a00ad","lessThan":"432b58cd959e594909a581b4974396cdbc9d4ca1","status":"affected","versionType":"git"},{"version":"62b5412b1f4afab27d8df90ddcabb8e1e11a00ad","lessThan":"41934f92e7a54d4080ac0b17aacc83224946785c","status":"affected","versionType":"git"},{"version":"62b5412b1f4afab27d8df90ddcabb8e1e11a00ad","lessThan":"ee8577de01c6b6c7dd1d76b52242c54d37a989f4","status":"affected","versionType":"git"},{"version":"62b5412b1f4afab27d8df90ddcabb8e1e11a00ad","lessThan":"63b269ec537dc0fd26d0bd64872c26860d108c9d","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98758","source_modified_at":"2026-10-19T09:25:11.783Z","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":"6.12.113","lessThanOrEqual":"6.12.*","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-2026-98758","source_modified_at":"2026-10-19T09:25:11.783Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"432b58cd959e594909a581b4974396cdbc9d4ca1","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98758","source_modified_at":"2026-10-19T09:25:11.783Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"41934f92e7a54d4080ac0b17aacc83224946785c","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98758","source_modified_at":"2026-10-19T09:25:11.783Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"63b269ec537dc0fd26d0bd64872c26860d108c9d","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05738,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:47:46.209Z","modified_at":"2026-10-19T09:25:11.783Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98758","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:25:11.783Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98758","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/432b58cd959e594909a581b4974396cdbc9d4ca1"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/41934f92e7a54d4080ac0b17aacc83224946785c"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ee8577de01c6b6c7dd1d76b52242c54d37a989f4"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/63b269ec537dc0fd26d0bd64872c26860d108c9d"}],"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":"2026-10-19T09:25:11.783Z","content_hash":"c738b01bf0809994cc1837fec7c5ea129d1f855985fd8d56fd497a27d2b509d6"}}
