Overview

What is CVE-2026-74510?

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: mgmt: fix UAF in pair command cancellation

The pairing completion and authentication failure callbacks look up the pending MGMT_OP_PAIR_DEVICE command by walking hdev->mgmt_pending. The lookup returned a command that was still linked on the shared pending list, without keeping mgmt_pending_lock held for the later dereference and removal.

A concurrent MGMT_OP_CANCEL_PAIR_DEVICE request can remove and free the same pending command before the callback uses it. The reverse race is also possible when cancel_pair_device() gets a command from pending_find() and a callback removes it before the cancel path dereferences it.

This can lead to a use-after-free and a second list_del().

Make the pairing lookup helpers transfer ownership of the pending command by removing it from hdev->mgmt_pending while holding mgmt_pending_lock. The callbacks and cancel path then complete the command and free it directly, so racing paths cannot find or free the same command again.

Take a temporary hci_conn reference in cancel_pair_device() because the command completion drops the reference stored in the pending command.
