CVE-2021-3658
This could lead to inadvertent exposure of the bluetooth stack to physically nearby attackers.
MEDIUM 6.5EPSS 0.79%
Does this matter?
Lower severity and a low EPSS score (0.79%). Track it; it rarely justifies an emergency change on its own.
Description
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.
