    CVE-2021-3658

    Published: 2 Mar 2022Last Modified: 8 Jul 2026

    Summary:

    Details: bluetoothd from bluez incorrectly saves adapters' Discoverable status when a device is powered down, and restores it when powered up. If a device is powered down while discoverable, it will be discoverable when powered on again. This could lead to inadvertent exposure of the bluetooth stack to physically nearby attackers.
