CVE-2026-74510

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the Bluetooth management component. The pairing completion and authentication failure callbacks search for the pending MGMT OP PAIR DEVICE command by traversing hdev->mgmt pending. Because the lookup returns a command that remains linked to the shared pending list without maintaining the mgmt pending lock, a race condition occurs. A concurrent MGMT OP CANCEL PAIR DEVICE request can remove and free the pending command before the callback accesses it. Conversely, cancel pair device() may retrieve a command via pending find() that is subsequently removed by a callback before the cancellation path dereferences it. This can result in a use-after-free and a secondary list del() operation.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
