What is CVE-2024-7139?

CVE-2024-7139 is a critical vulnerability arising from an unchecked buffer length in the handling of L2CAP packets within Silicon Labs Bluetooth products. A specially crafted L2CAP packet can lead to a buffer overflow, causing a denial of service by triggering an assert failure. In scenarios where a watchdog timer is not employed, the affected device may require a hard reset for recovery. This vulnerability underscores the importance of robust input validation and timely updates to mitigate potential risks associated with device operations in Bluetooth communications.
