Severity ?

8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

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.
