For an additional BIS, hci_bind_bis() obtains the\nparent from hci_conn_hash_lookup_big(), which returns a bare pointer.\nUnlinking the child then drops the parent's existing hold and can\nschedule it for disconnection while its socket is still using it.\n\nTake a hold on the parent before linking it and drop that hold if linking\nfails. A successful link transfers the hold to hci_conn_unlink().","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98459","source_modified_at":"2026-10-19T09:19:55.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"11dc486ed5d4626e6b92a23b67ed76cb6c48bfc9","lessThan":"ff28e6c67143c76ef50c3eac01f2fad411705f71","status":"affected","versionType":"git"},{"version":"fa224d0c094a458e9ebf5ea9b1c696136b7af427","lessThan":"03a91cdf6862fb351a74f035ad21e70112438552","status":"affected","versionType":"git"},{"version":"fa224d0c094a458e9ebf5ea9b1c696136b7af427","lessThan":"4e49206d9574a4c109480198e73aea34ad0ed7f6","status":"affected","versionType":"git"},{"version":"fa224d0c094a458e9ebf5ea9b1c696136b7af427","lessThan":"bbcd723ee7a84bc868142fd57717af88e54e555a","status":"affected","versionType":"git"},{"version":"fa224d0c094a458e9ebf5ea9b1c696136b7af427","lessThan":"4c94557dd02569efa6c1072a0439addaef9a5224","status":"affected","versionType":"git"},{"version":"6.6.67","lessThan":"6.6.158","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98459","source_modified_at":"2026-10-19T09:19:55.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.8","status":"affected"},{"version":"0","lessThan":"6.8","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-2026-98459","source_modified_at":"2026-10-19T09:19:55.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"03a91cdf6862fb351a74f035ad21e70112438552","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98459","source_modified_at":"2026-10-19T09:19:55.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"4e49206d9574a4c109480198e73aea34ad0ed7f6","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98459","source_modified_at":"2026-10-19T09:19:55.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"4c94557dd02569efa6c1072a0439addaef9a5224","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98459","source_modified_at":"2026-10-19T09:19:55.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6.6.158","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05726,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:15:08.537Z","modified_at":"2026-10-19T09:19:55.996Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98459","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:19:55.996Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98459","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/ff28e6c67143c76ef50c3eac01f2fad411705f71"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/03a91cdf6862fb351a74f035ad21e70112438552"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/4e49206d9574a4c109480198e73aea34ad0ed7f6"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/bbcd723ee7a84bc868142fd57717af88e54e555a"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/4c94557dd02569efa6c1072a0439addaef9a5224"}],"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":"2026-10-19T09:19:55.996Z","content_hash":"783ac7bad97765db4e8dfe37a0ec0b850ba09ab4f7a7655f59ff7e22434af838"}}
