A cancelled\nentry is leaked, as _hci_cmd_sync_cancel_entry() does not release\nentry->data when there is no destroy callback, and hci_cmd_sync_clear()\ncancels every pending entry when the controller is unregistered. Nothing\nelse reclaims it 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. The now-empty done label is\nreplaced by a direct return."}],"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":"827af4787e74e8df9e8e0677a69fbb15e0856d2f","lessThan":"e0cd7b34dc6b5414cac3d4cd376f73d3e9ffbd93","status":"affected","versionType":"git"},{"version":"827af4787e74e8df9e8e0677a69fbb15e0856d2f","lessThan":"481533b03985177ddc805e0bd12fc07e7adf9040","status":"affected","versionType":"git"},{"version":"827af4787e74e8df9e8e0677a69fbb15e0856d2f","lessThan":"414b365ecea6c30357adee6b8a7c5edc03a03575","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":"6.13","status":"affected"},{"version":"0","lessThan":"6.13","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-rc1","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":"6.13","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/e0cd7b34dc6b5414cac3d4cd376f73d3e9ffbd93"},{"url":"https://git.kernel.org/stable/c/481533b03985177ddc805e0bd12fc07e7adf9040"},{"url":"https://git.kernel.org/stable/c/414b365ecea6c30357adee6b8a7c5edc03a03575"}],"title":"Bluetooth: MGMT: free the HCI command when it is cancelled","x_generator":{"engine":"bippy-1.2.0"}}}}
