Vulnerability from github – Published: 2024-09-28 06:30 – Updated: 2024-09-28 06:30

Details

The specific flaw exists within the DLB_HostHeartBeat handler of the DLB protocol implementation. When parsing an AES key, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device.

Was ZDI-CAN-23241

Severity

8.8 (High)
