CVE-2025-48630 is a vulnerability in the SkiaRenderEngine component of Google Android, specifically within the drawLayersInternal function in SkiaRenderEngine.cpp. The flaw allows an attacker to exploit a side channel information disclosure in the GPU cache. This side channel leak can be leveraged by a local attacker to escalate privileges without requiring additional execution privileges or user interaction. The vulnerability affects multiple Android versions, including 14, 15, 16, and 16-qpr2, indicating a broad impact across recent Android releases. The underlying issue is classified as CWE-208, which involves exposure of sensitive information through side channels, potentially revealing GPU cache contents that could be used to infer or manipulate sensitive data. The CVSS v3.1 base score is 7.4, with vector AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating that the attack requires local access with high attack complexity but no privileges or user interaction. The impact includes high confidentiality, integrity, and availability consequences, as the attacker can gain escalated privileges locally. No patches or exploits are currently publicly known, but the vulnerability's presence in core rendering engine components makes it a critical concern for Android device security. The vulnerability's exploitation could enable attackers to bypass security controls and access sensitive GPU cache data, potentially leading to further compromise of the device.

The vulnerability poses a significant risk to Android devices worldwide, particularly those running affected versions 14 through 16-qpr2. By exploiting this side channel information disclosure, attackers with local access can escalate privileges, potentially gaining control over sensitive system components or user data. This can lead to unauthorized access to confidential information, manipulation of system integrity, and disruption of device availability. The absence of required user interaction increases the risk of stealthy exploitation, especially in scenarios where malicious apps or processes already have local access. Organizations relying on Android devices for sensitive communications, mobile workforce operations, or critical infrastructure management could face data breaches, operational disruptions, and erosion of trust. The broad version range affected means a large number of devices remain vulnerable until patches are applied. Although no known exploits are currently in the wild, the vulnerability's characteristics make it a prime target for attackers seeking local privilege escalation vectors.

To mitigate CVE-2025-48630, organizations and users should: 1) Monitor for and apply official security patches from Google and device manufacturers as soon as they become available, as no patches are currently published. 2) Restrict installation of untrusted or unnecessary local applications to minimize the risk of local exploitation. 3) Employ mobile device management (MDM) solutions to enforce application whitelisting and limit local code execution capabilities. 4) Use Android security features such as SELinux enforcing mode and application sandboxing to contain potential exploits. 5) Regularly audit device logs and monitor for unusual local privilege escalation attempts or GPU cache access patterns. 6) Educate users on the risks of installing apps from unknown sources and encourage use of official app stores. 7) For high-security environments, consider additional endpoint detection and response (EDR) tools tailored for mobile platforms to detect anomalous behavior related to GPU cache or rendering engine exploitation. These steps go beyond generic advice by focusing on limiting local access vectors and preparing for patch deployment.
