Description
A flaw was found in the Linux kernel's Intel Bluetooth driver. When processing hardware error events, the driver logs event data as a string without verifying that the received payload is properly null-terminated. A physically proximate attacker or compromised Bluetooth device could exploit this flaw by sending malformed error events to trigger a buffer over-read. This issue primarily leads to information disclosure of adjacent kernel memory into system logs, and could potentially result in a Denial of Service (DoS) if the system crashes.
