Overview
A critical vulnerability, CVE-2025-23100, has been identified in Samsung Mobile Processors, specifically in Exynos 1280, 2200, 1380, 1480, 2400 models. This vulnerability originates from the absence of a NULL check, leading to the potential for a Denial of Service (DoS) attack. Given the widespread use of these processors in mobile devices, the impact of this vulnerability is significant and requires immediate attention.

How the Exploit Works
The exploit takes advantage of an absent NULL check in the affected processors. An attacker can send specially crafted data to the processor, which due to the missing NULL check, may cause the system to crash, leading to a Denial of Service. Moreover, in some cases, this could also potentially lead to a system compromise or data leakage, escalating the impact of the vulnerability.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This pseudocode simulates a scenario where an attacker sends malicious data to the processor.
def send_malicious_data(target_processor):
data = get_malicious_data() # Function to generate malicious data
target_processor.process(data) # Send malicious data to the processorIn this example, `get_malicious_data()` represents a function that generates malicious data crafted to exploit the vulnerability. The `process()` function represents the method in the target processor that processes incoming data. The absence of a NULL check in this function leads to the system crash and potential data leakage.
