CVE-2025-32333 is a high-severity elevation of privilege vulnerability affecting Google Android version 14. The flaw exists in the startSpaActivityForApp function within the SpaActivity.kt source file, where a logic error leads to a cross-user permission bypass. This vulnerability allows a local attacker to escalate privileges without requiring additional execution privileges or user interaction. Specifically, the logic error in the code permits an attacker to perform actions or access resources as another user on the device, violating the intended permission boundaries. The vulnerability is classified under CWE-863 (Incorrect Authorization), indicating that the system fails to properly enforce access controls. The CVSS v3.1 base score of 7.8 reflects a high severity, with attack vector being local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No known exploits are reported in the wild yet, and no patches have been linked at the time of publication. The vulnerability's exploitation could allow malicious local applications or users to bypass security restrictions, potentially leading to unauthorized access to sensitive data, modification of system or application state, or denial of service on the affected Android device. Given that Android 14 is the affected version, devices running this OS version are at risk until a patch is applied.

For European organizations, this vulnerability poses a significant risk, especially for enterprises and government agencies that rely on Android devices for sensitive communications, data access, and operational tasks. The ability for a local attacker to escalate privileges without user interaction means that malicious apps or insiders could gain unauthorized access to confidential information or system functions. This could lead to data breaches, compromise of corporate mobile device management (MDM) controls, and disruption of critical mobile services. The high impact on confidentiality, integrity, and availability means that sensitive personal data protected under GDPR could be exposed or altered, leading to regulatory penalties and reputational damage. Additionally, sectors such as finance, healthcare, and critical infrastructure in Europe that use Android devices extensively could face operational risks if attackers exploit this vulnerability to disrupt services or exfiltrate data. The lack of known exploits in the wild currently provides a window for mitigation, but the vulnerability’s characteristics make it a prime candidate for rapid exploitation once weaponized.

European organizations should prioritize the following mitigation steps: 1) Immediate inventory and identification of all devices running Android 14 within their environment. 2) Apply official security patches from Google as soon as they become available; monitor Google’s security advisories and Android security bulletins closely. 3) Restrict installation of untrusted or third-party applications by enforcing strict app whitelisting and using enterprise app stores or MDM solutions to control app deployment. 4) Implement strict user privilege management on devices, limiting the ability of users or apps to gain local privileges unnecessarily. 5) Employ runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions capable of detecting anomalous privilege escalation behaviors on mobile devices. 6) Educate users about the risks of installing unknown apps and the importance of device security hygiene. 7) Consider deploying mobile threat defense (MTD) solutions that can detect and block exploitation attempts targeting local privilege escalation vulnerabilities. 8) Regularly audit device configurations and permissions to ensure compliance with security policies. These measures, combined with timely patching, will reduce the attack surface and mitigate the risk posed by this vulnerability.
