Technical Details of CVE-2017-8141

This section provides more technical insights into the CVE.

Vulnerability Description

An attacker with root privileges on the Android system can trick a user into installing a malicious app. The app can then initiate multiple threads and attempt to free specific memory, causing a double free scenario that may crash the system or allow for arbitrary code execution.

Affected Systems and Versions

Product: P10 Plus
Vendor: Huawei Technologies Co., Ltd.
Versions Affected: Versions earlier than VKY-AL00C00B153

Exploitation Mechanism

The vulnerability can be exploited when an attacker convinces a user to install a malicious app, which triggers the double memory freeing scenario, potentially leading to system crashes or the execution of arbitrary code.

Mitigation and Prevention

Protecting systems from CVE-2017-8141 requires immediate actions and long-term security practices.

Immediate Steps to Take

Update the affected devices to software version VKY-AL00C00B153 or later to mitigate the vulnerability.
Avoid installing apps from untrusted sources to reduce the risk of exploitation.

Long-Term Security Practices

Regularly update device software to patch known vulnerabilities.
Educate users about the risks of installing apps from unknown sources to prevent potential attacks.
Implement security measures to restrict root access and prevent unauthorized app installations.
Monitor for unusual app behavior that could indicate exploitation of vulnerabilities.

Patching and Updates

Ensure that all devices are updated to the latest software version provided by Huawei to address the memory double free vulnerability.
