CVE-2022-32614: Understanding the Potential Memory Corruption in Audio and How to Mitigate It

A recent vulnerability, CVE-2022-32614, has been discovered in the audio subsystem of certain devices. This vulnerability stands out due to its potential to cause memory corruption because of a logic error, leading to local escalation of privilege. Importantly, system execution privileges are needed to exploit this vulnerability, and user interaction is not required. In this blog post, we will take a deep dive into the details of this issue, including its background, code snippet, original references, and exploit details.

Background

The vulnerability with Identifier CVE-2022-32614 is associated with a potential memory corruption issue in the audio subsystem. As a critical security flaw, it could give malicious actors the ability to escalate privileges locally without requiring user interaction. The issue has been assigned Patch ID: ALPS07310571 and Issue ID: ALPS07310571.

Code Snippet

Although the precise code snippet associated with CVE-2022-32614 is not publicly available, the vulnerability is related to a logic error that results in a memory corruption. To give you an idea of how this exploit may occur, here is a simplified example:

#include<stdio.h>

int main ()
{
    int x = 5;
    int y = ;

    if (x > ) {
        if (y > ) {
            x = x / y;
        } else {
            printf("Error: Division by zero");
            return -1;
        }
    }

     // At this point, x may be corrupted, causing unexpected behavior.

    printf("x = %d\n", x);

    return ;
}

In this example, the conditional statement may result in a division by zero error that could corrupt memory. Although this is a simplified example, similar logic errors could cause memory corruption in the audio subsystem related to CVE-2022-32614.
