Page history
Changes are dated when recorded; day views use the last saved version from that UTC day, and citations stay fixed.
CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Bluetooth: MGMT: free the mesh send cancel command when it is cancelled
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: free the mesh send cancel command when it is cancelled
mesh_send_cancel() queues the pending command with a NULL destroy
callback, so it is only freed if send_cancel() runs. A cancelled entry is
leaked, as _hci_cmd_sync_cancel_entry() does not release entry->data when
there is no destroy callback, and hci_cmd_sync_clear() cancels every
pending entry when the controller is unregistered. Nothing else reclaims
it either: mgmt_pending_new() does not put the command on
hdev->mgmt_pending.
The leak also pins the socket reference taken by mgmt_pending_new(), so
the mgmt socket is never released.
Free the command from a destroy callback.
