{"schema":"threatline.record/2","record":{"id":"CVE-2026-98295","aliases":[],"summary":"Bluetooth: coredump: Quiesce dump work on unregister","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: coredump: Quiesce dump work on unregister\n\nhci_devcd_handle_pkt_init() arms dump_timeout and coredump producers\nqueue dump_rx without holding an hdev reference. Unregister leaves both\nworks live, so disconnecting during an active dump lets them access hdev\nafter hci_release_dev() frees it.\n\nShut down coredump processing during unregister. Close the producer gate\nunder dump_q.lock before disabling both works, then free the active buffer\nand queued packets under hci_dev_lock. Serializing the gate with enqueue\nprevents controller-specific workers from adding packets after the final\npurge.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98295","source_modified_at":"2026-10-19T09:17:06.302Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"9695ef876fd122cb7bbc04a4a93b8727d2e36bda","lessThan":"24af375d7d8aa5f698e4dc41317102f44114351a","status":"affected","versionType":"git"},{"version":"9695ef876fd122cb7bbc04a4a93b8727d2e36bda","lessThan":"dcaf10ef27f928568c25de3e9fc242e538de5c67","status":"affected","versionType":"git"},{"version":"9695ef876fd122cb7bbc04a4a93b8727d2e36bda","lessThan":"82699d1b727ba5980b94f1eb8dc3d346f41b7c67","status":"affected","versionType":"git"},{"version":"9695ef876fd122cb7bbc04a4a93b8727d2e36bda","lessThan":"d236517c264e41dc09833c708ef23bccb7a91219","status":"affected","versionType":"git"},{"version":"deb8156ebe5cb63a5988e7f86cc46aa062527c2b","status":"affected","versionType":"git"},{"version":"6.1.188","lessThan":"6.2","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98295","source_modified_at":"2026-10-19T09:17:06.302Z","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":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.54","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.8","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-2026-98295","source_modified_at":"2026-10-19T09:17:06.302Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"24af375d7d8aa5f698e4dc41317102f44114351a","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98295","source_modified_at":"2026-10-19T09:17:06.302Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"82699d1b727ba5980b94f1eb8dc3d346f41b7c67","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98295","source_modified_at":"2026-10-19T09:17:06.302Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6.2","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00175,"percentile":0.06676,"score_date":"2026-10-23"},"published_at":"2026-10-06T08:45:54.141Z","modified_at":"2026-10-19T09:17:06.302Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98295","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:17:06.302Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98295","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/24af375d7d8aa5f698e4dc41317102f44114351a"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/dcaf10ef27f928568c25de3e9fc242e538de5c67"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/82699d1b727ba5980b94f1eb8dc3d346f41b7c67"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/d236517c264e41dc09833c708ef23bccb7a91219"}],"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":"2026-10-19T09:17:06.302Z","content_hash":"abc3b6d7964f3aad9af47a5740815f49fdf7cfca961db3adc84ea456a3ec1701"}}
