CVE-2023-47859

Local denial of service via undisclosed access-control failure

Published May 16, 2024 · Updated Aug 2, 2024

Improper access control in Intel Wireless Bluetooth before 23.20 allows local users to interrupt Bluetooth availability through local access. Intel identifies the access-control failure but has not disclosed the affected driver component, the authorization decision that fails, or the input path that reaches it. Successful exploitation requires low-privileged local access on Windows 10 or Windows 11; Intel reports availability loss only, without confidentiality or integrity impact.
