CVE-2026-0010 in Android
Summary
by MITRE • 03/02/2026
In onTransact of IDrmManagerService.cpp, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

The vulnerability identified as CVE-2026-0010 represents a critical out-of-bounds write flaw within the Android framework's DRM management system. This issue exists in the onTransact method of the IDrmManagerService.cpp component, which serves as a crucial interface for digital rights management operations within the Android operating system. The flaw stems from the absence of proper bounds checking mechanisms when processing incoming transaction data, creating a pathway for malicious code to write beyond allocated memory boundaries. Such vulnerabilities are particularly dangerous because they can be exploited without requiring any user interaction or additional privileges beyond what is normally available to an application, making them highly attractive targets for attackers seeking to escalate their privileges within the system.
The technical nature of this vulnerability places it squarely within the realm of CWE-129, which specifically addresses insufficient bounds checking in software systems. This weakness allows attackers to manipulate memory structures through crafted input data, potentially leading to arbitrary code execution or privilege escalation. The onTransact method serves as a core part of Android's inter-process communication framework, where it handles incoming Binder transactions between different processes. When this method fails to validate the size or content of incoming data before processing, it creates opportunities for attackers to craft malicious payloads that can overwrite adjacent memory locations. The absence of bounds checking in this critical system component means that any application with access to the DRM service interface could potentially exploit this vulnerability to gain elevated privileges.
The operational impact of CVE-2026-0010 extends far beyond simple memory corruption, as it enables local privilege escalation attacks that can fundamentally compromise system security. An attacker who successfully exploits this vulnerability could potentially gain root-level access to the Android device, allowing them to modify system files, install malicious applications, or extract sensitive data from protected areas of the device. This type of vulnerability aligns with ATT&CK technique T1068, which covers the use of legitimate credentials and system privileges for escalation purposes. The local nature of the exploit means that it could be leveraged by malware already present on the device or by attackers who have gained access through other means, making it particularly concerning for mobile security. The lack of user interaction requirements significantly reduces the attack surface and increases the likelihood of successful exploitation in real-world scenarios.
Mitigation strategies for this vulnerability must address both the immediate security risk and the underlying architectural issues that enabled the flaw. Device manufacturers and security teams should prioritize applying the relevant security patches that include proper bounds checking mechanisms in the DRM service implementation. The fix should involve implementing comprehensive input validation that verifies the size and content of all data received through the onTransact method before any processing occurs. Additionally, system administrators should consider implementing runtime monitoring and anomaly detection systems that can identify suspicious memory access patterns that might indicate exploitation attempts. The solution should also include code review processes that specifically focus on identifying similar vulnerabilities in other components of the Android framework, particularly those handling inter-process communication. Security hardening measures such as address space layout randomization and stack canaries should be enabled to make exploitation more difficult even if similar flaws exist in other parts of the system. Organizations should also consider implementing application sandboxing and privilege separation mechanisms to limit the potential damage from successful exploitation attempts.
