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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["include/net/bluetooth/coredump.h","net/bluetooth/coredump.c","net/bluetooth/hci_core.c"],"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"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["include/net/bluetooth/coredump.h","net/bluetooth/coredump.c","net/bluetooth/hci_core.c"],"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-rc4","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.12.112"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.18.54"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"7.2.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"7.3-rc4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1.188"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/24af375d7d8aa5f698e4dc41317102f44114351a"},{"url":"https://git.kernel.org/stable/c/dcaf10ef27f928568c25de3e9fc242e538de5c67"},{"url":"https://git.kernel.org/stable/c/82699d1b727ba5980b94f1eb8dc3d346f41b7c67"},{"url":"https://git.kernel.org/stable/c/d236517c264e41dc09833c708ef23bccb7a91219"}],"title":"Bluetooth: coredump: Quiesce dump work on unregister","x_generator":{"engine":"bippy-1.2.0"}}}}
