{"schema":"threatline.record/2","record":{"id":"CVE-2026-98458","aliases":[],"summary":"Bluetooth: ISO: release unused CIS holds after channel attach","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: ISO: release unused CIS holds after channel attach\n\nhci_bind_cis() and hci_connect_cis() return one hci_conn hold for the\nISO layer.  A new channel association consumes that hold, which is\neventually released by iso_conn_free().\n\nThere are two cases where iso_chan_add() does not create an association:\nit returns success when the socket is already attached to the same\niso_conn, and it returns -EBUSY when another socket is attached.  The\nhold returned for the current call is unused in both cases.  This occurs\nwhen deferred setup calls iso_connect_cis() again for its existing\nsocket, or when another socket attempts to reuse the CIS.\n\nDetect the idempotent case while the connection is locked and release\nthe unused hold after iso_chan_add().  Also release it on -EBUSY.  Do not\ndrop it for other errors: a newly allocated iso_conn releases the\ntransferred hold when its last temporary reference is put.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98458","source_modified_at":"2026-10-19T09:19:54.818Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"69997d50ec574be816b4ee8f9cee52ebbd53f8bd","lessThan":"e0e8b70207eaf27aee0a05ec5bf2d1b6bcb004d1","status":"affected","versionType":"git"},{"version":"69997d50ec574be816b4ee8f9cee52ebbd53f8bd","lessThan":"ed4c026cc4094dfb7a329b9d8df0ddd0be1b2458","status":"affected","versionType":"git"},{"version":"69997d50ec574be816b4ee8f9cee52ebbd53f8bd","lessThan":"e5fcca51177f224604e3a8c926ffd5edbeb58b09","status":"affected","versionType":"git"},{"version":"69997d50ec574be816b4ee8f9cee52ebbd53f8bd","lessThan":"0fcd4dad555c96e0bd3a1b8c569f989be85c7341","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98458","source_modified_at":"2026-10-19T09:19:54.818Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.6","status":"affected"},{"version":"0","lessThan":"6.6","status":"unaffected","versionType":"semver"},{"version":"6.12.113","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-2026-98458","source_modified_at":"2026-10-19T09:19:54.818Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"0fcd4dad555c96e0bd3a1b8c569f989be85c7341","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00209,"percentile":0.10484,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:15:07.572Z","modified_at":"2026-10-19T09:19:54.818Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98458","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:19:54.818Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98458","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/e0e8b70207eaf27aee0a05ec5bf2d1b6bcb004d1"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ed4c026cc4094dfb7a329b9d8df0ddd0be1b2458"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e5fcca51177f224604e3a8c926ffd5edbeb58b09"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/0fcd4dad555c96e0bd3a1b8c569f989be85c7341"}],"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":"2026-10-19T09:19:54.818Z","content_hash":"655236b72f955616df108c608a7c13b4df6bd0114c4334622220983e6907acd0"}}
