Overview

The vulnerability, designated CVE-2025-26452, is a serious flaw in ResourcesImpl.java, specifically in the loadDrawableForCookie function. It allows potential culprits to access task snapshots of other applications, leading to a possible local escalation of privilege. This means that any app installed on the device could potentially exploit this flaw and gain unauthorized access to sensitive data.

How the Exploit Works

The vulnerability resides in the `loadDrawableForCookie` function of `ResourcesImpl.java`. This function doesn’t properly validate input, allowing an attacker to manipulate the process and gain access to task snapshots of other apps. With these snapshots, an attacker could escalate their privileges on the local system, potentially compromising the device or leaking sensitive data.

Conceptual Example Code

The following code snippet illustrates a potential manner in which this vulnerability could be exploited:

public class Exploit {
public static void main(String[] args) {
// Obtain an instance of ResourcesImpl
ResourcesImpl resources = getResourcesImplInstance();
// Prepare a malicious cookie
Object maliciousCookie = prepareMaliciousCookie();
// Exploit the vulnerability
resources.loadDrawableForCookie(null, maliciousCookie);
}
}

In this conceptual example, an attacker prepares a malicious cookie that, when passed to the `loadDrawableForCookie` method, triggers the vulnerability and allows the attacker to access task snapshots of other apps.

Mitigation Guidance

To mitigate this vulnerability, users are strongly advised to apply the latest update from the vendor. In the absence of a vendor patch, employing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary measure. However, these are not long-term solutions and can only help detect or prevent exploitation attempts. They do not eliminate the vulnerability from the system.
