{"id":"CVE-2026-98295","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.","modified":"2026-10-08T02:52:56.707697918Z","published":"2026-10-06T08:45:54.141Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98295.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/24af375d7d8aa5f698e4dc41317102f44114351a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82699d1b727ba5980b94f1eb8dc3d346f41b7c67"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d236517c264e41dc09833c708ef23bccb7a91219"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dcaf10ef27f928568c25de3e9fc242e538de5c67"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98295.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98295"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"9695ef876fd122cb7bbc04a4a93b8727d2e36bda"},{"fixed":"24af375d7d8aa5f698e4dc41317102f44114351a"},{"fixed":"dcaf10ef27f928568c25de3e9fc242e538de5c67"},{"fixed":"82699d1b727ba5980b94f1eb8dc3d346f41b7c67"},{"fixed":"d236517c264e41dc09833c708ef23bccb7a91219"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.1.188"},{"fixed":"6.2"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"deb8156ebe5cb63a5988e7f86cc46aa062527c2b"}]}],"versions":["v6.1.189","v6.1.188"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98295.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.4.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98295.json"}}],"schema_version":"1.9.0"}
