{"id":"CVE-2026-90253","summary":"Bluetooth: MGMT: free the mesh send cancel command when it is cancelled","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: MGMT: free the mesh send cancel command when it is cancelled\n\nmesh_send_cancel() queues the pending command with a NULL destroy\ncallback, so it is only freed if send_cancel() runs. A cancelled entry is\nleaked, as _hci_cmd_sync_cancel_entry() does not release entry-\u003edata 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-\u003emgmt_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.","modified":"2026-09-18T03:48:36.635638860Z","published":"2026-09-17T16:07:53.435Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90253.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/05438d338a875a9daa08ca3f6a35b4480cf13de4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3c742feda8fcabf741a17bcf668b63c8f606f9c5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/416fabca9b7237b76aa9cafcf8c497b8ac00d88c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/88e30d036d777b00aed42bd35000de23ff40910c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b609341ee56967d9a45845ff26f79336d2114b55"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fa46d428c014e7b72a18634679815670418e67dc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90253.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90253"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b338d91703fae6f6afd67f3f75caa3b8f36ddef3"},{"fixed":"b609341ee56967d9a45845ff26f79336d2114b55"},{"fixed":"416fabca9b7237b76aa9cafcf8c497b8ac00d88c"},{"fixed":"88e30d036d777b00aed42bd35000de23ff40910c"},{"fixed":"05438d338a875a9daa08ca3f6a35b4480cf13de4"},{"fixed":"fa46d428c014e7b72a18634679815670418e67dc"},{"fixed":"3c742feda8fcabf741a17bcf668b63c8f606f9c5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90253.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90253.json"}}],"schema_version":"1.9.0"}
