The issue allows attackers to execute arbitrary code or cause a denial of service due to an incorrect pointer dereference. This can be achieved via an application that uses crafted arguments in a local `diagchar ioctl` call.

The issue is related to an integer overflow in the diagchar core.c file of the Qualcomm Innovation Center (QuIC) Diagnostics kernel-mode driver. This allows attackers to execute arbitrary code or cause a denial of service via an application that uses crafted arguments in a local `diagchar ioctl` call.
