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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/24af375d7d8aa5f698e4dc41317102f44114351a","https://git.kernel.org/stable/c/82699d1b727ba5980b94f1eb8dc3d346f41b7c67","https://git.kernel.org/stable/c/d236517c264e41dc09833c708ef23bccb7a91219","https://git.kernel.org/stable/c/dcaf10ef27f928568c25de3e9fc242e538de5c67"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98295","score":0.00168,"percentile":0.06044,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
