CVE-2025-57840 is a vulnerability identified in Honor's Magic OS, specifically affecting the Android Debug Bridge (ADB) component. The issue is categorized under CWE-269, which denotes improper privilege management. This vulnerability allows a local attacker with low privileges to bypass certain privilege restrictions within the ADB service. The CVSS 3.1 base score is 2.2, indicating low severity, with the vector AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:L/A:N. This means the attack requires local access (AV:L), high attack complexity (AC:H), low privileges (PR:L), and user interaction (UI:R). The scope is unchanged (S:U), with no confidentiality or availability impact (C:N, A:N), but a limited integrity impact (I:L). The vulnerability could potentially allow an attacker to perform actions within the ADB context that they should not be authorized to do, possibly leading to minor integrity violations. However, exploitation is constrained by the need for local access, user interaction, and high complexity, reducing the risk of widespread exploitation. No known exploits have been reported in the wild, and no patches have been published as of the information date. The vulnerability highlights the importance of proper privilege management in system components like ADB, which are critical for device debugging and development but can be attack vectors if misconfigured or improperly secured.

For European organizations, the impact of CVE-2025-57840 is limited due to its low severity and exploitation constraints. The vulnerability requires local access and user interaction, making remote or automated attacks unlikely. However, in environments where Honor Magic OS devices are used extensively, especially in development, testing, or internal IT operations where ADB might be enabled, there is a risk of privilege escalation or unauthorized actions within the ADB service. This could lead to minor integrity issues, such as unauthorized modification of debugging settings or limited unauthorized commands execution. The lack of confidentiality and availability impact means sensitive data exposure or service disruption is not a concern. Nonetheless, organizations should be cautious in environments with shared or less controlled device access, as attackers with physical or local access could exploit this vulnerability to gain elevated privileges within the ADB context. The threat is more relevant for organizations relying on mobile device management or development involving Honor Magic OS devices.

To mitigate CVE-2025-57840, European organizations should implement the following specific measures: 1) Disable ADB on Honor Magic OS devices unless explicitly needed for development or debugging purposes. 2) Restrict physical and local access to devices, ensuring only trusted personnel can interact with them. 3) Enforce strict user authentication and authorization policies for device access, especially where ADB is enabled. 4) Monitor device logs and ADB usage for unusual or unauthorized activity. 5) Apply principle of least privilege by limiting user accounts that can interact with ADB. 6) Stay informed about vendor updates and apply patches promptly once available. 7) Use mobile device management (MDM) solutions to centrally control and audit device configurations, including ADB settings. 8) Educate users about the risks of enabling debugging features and the importance of device security. These steps go beyond generic advice by focusing on controlling ADB access and monitoring within the specific context of Honor Magic OS devices.
