CVE-2025-23101 is a Use-After-Free (UAF) vulnerability identified in the Samsung Mobile Processor Exynos 1380. A Use-After-Free occurs when a program continues to use a pointer after the memory it points to has been freed, potentially leading to undefined behavior including memory corruption, crashes, or privilege escalation. In this case, the vulnerability allows an attacker to escalate privileges on the affected mobile processor. The CVSS v3.1 base score is 6.5 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and low impact on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). This suggests that the vulnerability can be exploited remotely without authentication or user interaction, making it relatively accessible to attackers. The lack of patch links and absence of known exploits in the wild indicate that the vulnerability is newly disclosed and may not yet be actively exploited. However, the potential for privilege escalation on a widely used mobile processor is significant, as it could allow attackers to gain elevated control over the device, bypass security mechanisms, and potentially access sensitive data or install persistent malware. The vulnerability is specifically tied to the Exynos 1380 processor, which is used in certain Samsung mobile devices. No specific affected versions or products are listed, which may indicate that the vulnerability affects all devices using this processor or that detailed information is not yet publicly available. The CWE classification is CWE-416, confirming the Use-After-Free nature of the flaw.

For European organizations, the impact of CVE-2025-23101 primarily concerns employees and users who rely on Samsung mobile devices powered by the Exynos 1380 processor. If exploited, attackers could escalate privileges on these devices, potentially gaining unauthorized access to corporate data, communications, and applications. This could lead to data breaches, espionage, or disruption of business operations. The vulnerability's network attack vector and lack of required privileges or user interaction increase the risk of remote exploitation, possibly through malicious apps, network attacks, or compromised websites. Organizations with Bring Your Own Device (BYOD) policies or mobile workforce using vulnerable Samsung devices are particularly at risk. Additionally, the vulnerability could be leveraged in targeted attacks against high-value individuals or sectors such as finance, government, or critical infrastructure within Europe. However, since no known exploits are currently in the wild and no patches are yet available, the immediate risk is moderate but could escalate rapidly once exploit code is developed or disclosed.

1. Monitor Samsung and Exynos security advisories closely for official patches or firmware updates addressing CVE-2025-23101 and apply them promptly once available. 2. Implement mobile device management (MDM) solutions to enforce security policies, control app installations, and remotely manage or quarantine vulnerable devices. 3. Restrict installation of untrusted or third-party applications on corporate devices to reduce the risk of exploitation via malicious apps. 4. Educate users about the risks of installing apps from unofficial sources and the importance of applying updates. 5. Employ network-level protections such as firewalls and intrusion detection systems to monitor and block suspicious traffic targeting mobile devices. 6. For high-risk environments, consider restricting or isolating the use of vulnerable Samsung devices until patches are available. 7. Conduct regular security assessments and audits of mobile device usage within the organization to identify and mitigate exposure. 8. Collaborate with mobile security vendors to deploy endpoint protection solutions capable of detecting exploitation attempts related to Use-After-Free vulnerabilities.
