CVE-2025-48641 is a vulnerability identified in multiple functions of the Nfc.h component within Google Android versions 14 through 16-qpr2. The root cause is a race condition that leads to a use-after-free scenario, where memory is accessed after it has been freed, potentially allowing an attacker to execute arbitrary code or escalate privileges locally. This vulnerability does not require the attacker to have additional execution privileges beyond low-level local access, nor does it require any user interaction, making it easier to exploit in scenarios where an attacker already has limited access to the device. The vulnerability is classified under CWE-362, indicating a concurrency issue that can cause unsafe memory operations. The CVSS v3.1 base score is 7.0, reflecting high severity due to the potential for complete compromise of confidentiality, integrity, and availability, combined with the complexity of exploitation being high (AC:H) but requiring only low privileges (PR:L) and no user interaction (UI:N). Although no public exploits are currently known, the vulnerability poses a significant risk to Android devices, especially those with NFC enabled, as the NFC subsystem is directly implicated. The lack of available patches at the time of publication necessitates vigilance and proactive mitigation by users and organizations. This vulnerability could be leveraged by malicious local actors or malware to gain elevated privileges and potentially control the device or access sensitive data.

The impact of CVE-2025-48641 is substantial for organizations and individuals using affected Android versions, particularly those with NFC functionality enabled. Successful exploitation allows an attacker with local access to escalate privileges without requiring user interaction, potentially leading to full device compromise. This could result in unauthorized access to sensitive data, installation of persistent malware, disruption of device functionality, and lateral movement within enterprise environments. For organizations, this elevates risks related to data breaches, espionage, and operational disruption, especially in sectors relying heavily on mobile devices such as finance, healthcare, government, and critical infrastructure. The vulnerability's presence in multiple Android versions increases the scope of affected devices globally. Given the widespread use of Android, the potential for exploitation in targeted attacks or malware campaigns is significant, particularly in environments where physical or local access controls are weak. The absence of known exploits currently provides a window for mitigation but also underscores the need for rapid patch deployment once available.

To mitigate CVE-2025-48641, organizations and users should: 1) Monitor Google’s official security advisories and apply patches immediately once they are released for affected Android versions. 2) Restrict local access to devices by enforcing strong physical security controls and limiting the ability of untrusted users to interact with devices. 3) Disable NFC functionality on devices where it is not required to reduce the attack surface. 4) Employ mobile device management (MDM) solutions to enforce security policies, monitor device behavior, and quickly respond to suspicious activities. 5) Educate users about the risks of local privilege escalation and the importance of device security hygiene. 6) Implement runtime protections such as SELinux policies and exploit mitigation technologies that can help prevent exploitation of use-after-free vulnerabilities. 7) Conduct regular security audits and vulnerability assessments on mobile device fleets to identify and remediate potential weaknesses. These steps go beyond generic advice by focusing on reducing local attack vectors and hardening the NFC subsystem exposure until patches are available.
