CVE-2025-22413 is a medium-severity vulnerability affecting the Android kernel, specifically within multiple functions of the hyp-main.c source file. The vulnerability arises from a logic error in the kernel code, which leads to a possible privilege escalation scenario resulting in local information disclosure. Notably, exploitation of this vulnerability does not require any additional execution privileges or user interaction, making it potentially easier for an attacker with local access to leverage it. The vulnerability is categorized under CWE-703, which relates to improper check or handling of exceptional conditions, indicating that the logic flaw may cause the kernel to leak sensitive information unintentionally. Since the flaw is in the kernel, the impact is at a low level of the operating system, potentially exposing sensitive kernel or system memory data to unprivileged local users or applications. However, the vulnerability does not affect integrity or availability, as it is limited to confidentiality impact only. The CVSS v3.1 base score is 4.0, reflecting a low attack vector (local), low complexity, no privileges required, no user interaction, and limited impact to confidentiality only. There are no known exploits in the wild at the time of publication, and no patches have been linked yet, indicating that mitigation may require monitoring for vendor updates. Given the nature of the vulnerability, it is primarily a concern for local attackers or malicious applications that have already gained some form of local access but lack elevated privileges. The flaw could be used to gather sensitive information from the kernel memory space, which could aid in further attacks or privilege escalations if combined with other vulnerabilities.

For European organizations, the impact of CVE-2025-22413 depends largely on the prevalence of Android devices within their environment and the sensitivity of the data stored or processed on those devices. Since the vulnerability allows local information disclosure without privilege escalation or user interaction, it poses a risk primarily to environments where untrusted or potentially malicious applications can be installed or where physical access to devices is possible. Enterprises with Bring Your Own Device (BYOD) policies or those that rely heavily on Android devices for sensitive operations could face risks of data leakage or reconnaissance by attackers aiming to gather kernel-level information. While the vulnerability does not directly allow code execution or system compromise, the disclosed information could be leveraged in multi-stage attacks, especially in targeted espionage or advanced persistent threat (APT) scenarios. This is particularly relevant for sectors such as government, defense, finance, and critical infrastructure within Europe, where data confidentiality is paramount. Additionally, since no user interaction is required, the vulnerability could be exploited silently by malicious apps or insiders with local access. The lack of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation once details become more widely known.

To mitigate CVE-2025-22413 effectively, European organizations should: 1) Monitor official Google and Android security advisories closely for patches addressing this vulnerability and prioritize timely deployment once available. 2) Implement strict application control policies on Android devices, limiting installation to trusted sources and using Mobile Device Management (MDM) solutions to enforce app vetting and permissions. 3) Restrict physical access to Android devices, especially in sensitive environments, to prevent local exploitation. 4) Employ runtime protection and behavior monitoring on Android devices to detect anomalous local processes that might attempt to exploit kernel vulnerabilities. 5) Educate users about the risks of installing untrusted applications and the importance of device security hygiene. 6) Consider deploying endpoint detection and response (EDR) tools capable of monitoring Android devices for suspicious local activity. 7) For organizations developing Android-based products or custom ROMs, conduct thorough code reviews focusing on kernel logic and error handling to prevent similar logic errors. These steps go beyond generic patching advice by emphasizing proactive device management, access control, and monitoring tailored to the nature of this local information disclosure vulnerability.
