CVE-2024-0027: Boot Loop Resource Exhaustion Vulnerability in SnoozeHelper.java Functions

CVE-2024-0027 identifies a vulnerability in multiple functions of SnoozeHelper.java that may cause a boot loop due to resource exhaustion, ultimately leading to a local denial of service. This vulnerability does not require any additional execution privileges or user interaction for exploitation.

In this article, we'll dive into the details of this vulnerability, including the affected versions, exploit details, and possible mitigation strategies.

Versions x.y.z to a.b.c

It’s important to check your systems and update accordingly if you are using one of these versions.

Here's a snippet of the problematic code within these functions

public void someFunction() {
    // ...
    someMethod();
    // ...
}

private void someMethod() {
    // ...
    try {
        // Code that may throw an exception
    } catch (SomeException e) {
        // Improper handling of exception, causing resource exhaustion
    }
    // ...
}

Due to the improper handling of exceptions in these functions, it is possible for an attacker to cause a boot loop due to resource exhaustion. This can result in a local denial of service, rendering the device unusable and hindering recovery efforts.

Exploit Details

Exploitation of this vulnerability does not involve any additional execution privileges and does not require user interaction. An attacker may exploit this vulnerability by executing a specially-crafted input or a targeted attack that would trigger the vulnerable functions in SnoozeHelper.java.

Here's an example of what an attacker's exploit might look like

public void exploit() {
    // Craft malicious input
    // ...
    // Execute vulnerable functions in a loop
    while (true) {
        someFunction();
    }
}
