Technical ContextAI · show details
This vulnerability is classified as Use After Free (CWE-416), which allows attackers to access freed memory to execute arbitrary code or crash the application. The Trusted Execution Environment (TEE) module driver of Mate 9 and Mate 9 Pro smart phones with software versions earlier than MHA-AL00BC00B221 and versions earlier than LON-AL00BC00B221 has a use after free (UAF) vulnerability. An attacker tricks a user into installing a malicious application, and the application can start multiple threads and try to create and free specific memory, which could triggers access memory after free it and causes a system crash or arbitrary code execution. Affected products include: Huawei Mate 9 Firmware, Huawei Mate 9 Pro Firmware.

SSVC AssessmentENISA
Priority Score
Attack Technique
Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
