Does this matter?

Lower severity and a low EPSS score (0.12%). Track it; it rarely justifies an emergency change on its own.

Description

A flaw was found in BlueZ. An out-of-bounds read vulnerability exists in the btmon Bluetooth monitor tool when processing crafted HCI Return Link Keys events. A maliciously crafted btsnoop capture file can specify a large number of link keys that exceeds the actual packet data, causing btmon to read beyond the allocated buffer and crash.
