A cancelled entry is\nleaked, as _hci_cmd_sync_cancel_entry() does not release entry->data when\nthere is no destroy callback, and hci_cmd_sync_clear() cancels every\npending entry when the controller is unregistered. Nothing else reclaims\nit either: mgmt_pending_new() does not put the command on\nhdev->mgmt_pending.\n\nThe leak also pins the socket reference taken by mgmt_pending_new(), so\nthe mgmt socket is never released.\n\nFree the command from a destroy callback." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "net/bluetooth/mgmt.c" ], "versions": [ { "version": "b338d91703fae6f6afd67f3f75caa3b8f36ddef3", "lessThan": "b609341ee56967d9a45845ff26f79336d2114b55", "status": "affected", "versionType": "git" }, { "version": "b338d91703fae6f6afd67f3f75caa3b8f36ddef3", "lessThan": "416fabca9b7237b76aa9cafcf8c497b8ac00d88c", "status": "affected", "versionType": "git" }, { "version": "b338d91703fae6f6afd67f3f75caa3b8f36ddef3", "lessThan": "88e30d036d777b00aed42bd35000de23ff40910c", "status": "affected", "versionType": "git" }, { "version": "b338d91703fae6f6afd67f3f75caa3b8f36ddef3", "lessThan": "05438d338a875a9daa08ca3f6a35b4480cf13de4", "status": "affected", "versionType": "git" }, { "version": "b338d91703fae6f6afd67f3f75caa3b8f36ddef3", "lessThan": "fa46d428c014e7b72a18634679815670418e67dc", "status": "affected", "versionType": "git" }, { "version": "b338d91703fae6f6afd67f3f75caa3b8f36ddef3", "lessThan": "3c742feda8fcabf741a17bcf668b63c8f606f9c5", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "net/bluetooth/mgmt.c" ], "versions": [ { "version": "6.1", "status": "affected" }, { "version": "0", "lessThan": "6.1", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.188", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.157", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.110", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.18.52", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.2.6", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.3", "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": "6.1", "versionEndExcluding": "6.1.188" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.1", "versionEndExcluding": "6.6.157" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.1", "versionEndExcluding": "6.12.110" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.1", "versionEndExcluding": "6.18.52" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.1", "versionEndExcluding": "7.2.6" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.1", "versionEndExcluding": "7.3" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/b609341ee56967d9a45845ff26f79336d2114b55" }, { "url": "https://git.kernel.org/stable/c/416fabca9b7237b76aa9cafcf8c497b8ac00d88c" }, { "url": "https://git.kernel.org/stable/c/88e30d036d777b00aed42bd35000de23ff40910c" }, { "url": "https://git.kernel.org/stable/c/05438d338a875a9daa08ca3f6a35b4480cf13de4" }, { "url": "https://git.kernel.org/stable/c/fa46d428c014e7b72a18634679815670418e67dc" }, { "url": "https://git.kernel.org/stable/c/3c742feda8fcabf741a17bcf668b63c8f606f9c5" } ], "title": "Bluetooth: MGMT: free the mesh send cancel command when it is cancelled", "x_generator": { "engine": "bippy-1.2.0" } } } }
