Overview

The vulnerability, identified as CVE-2024-49196, is a serious issue discovered in the GPU of Samsung Mobile Processor Exynos 1480 and 2400. This type confusion vulnerability can potentially lead to a Denial of Service (DoS), compromising system integrity and possibly resulting in data leakage. It is of utmost importance that users and administrators of devices using these processors understand the severity of this vulnerability and take immediate action to mitigate its risks.

How the Exploit Works

This vulnerability exploits type confusion within the GPU of the affected Samsung Mobile Processors. An attacker, with low-level privileges and user interaction, can send a maliciously crafted payload to the GPU. The GPU, failing to correctly identify the type of the incoming data, tries to process it, leading to a Denial of Service condition. This can potentially compromise the system and lead to data leakage.

Conceptual Example Code

Here is a
conceptual
example of how the vulnerability might be exploited. This hypothetical shell command represents a malicious payload causing the type confusion:

$ echo "{ 'type': 'GPU_Process', 'data': 'malicious_payload' }" > /dev/exynos_gpu

In this example, the attacker is echoing a JSON string into the Exynos GPU device file. The ‘type’ field is set to ‘GPU_Process’, but the ‘data’ field contains a malicious payload that the GPU cannot correctly process, leading to a Denial of Service.
