The issue is related to a stack overflow in the touchscreen drive. An attacker can exploit this by tricking a user into installing a malicious application on the smartphone and sending a specific parameter to the touchscreen drive, which can cause the system to crash or escalate privileges.

The touchscreen driver has a heap overflow issue, allowing attackers to crash the system or escalate user privileges.

The issue allows attackers to disable the PXN defense mechanism, potentially leading to system crashes or privilege escalation by invoking related drive code.

A heap-based buffer overflow in the HIFI driver allows attackers to cause a denial of service (reboot) or execute arbitrary code via a crafted application.
