Name of the Vulnerable Software and Affected Versions Xiaomi Mi6 Browser versions prior to 10.4.0

Description This issue allows remote attackers to execute arbitrary code on vulnerable installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The specific flaw exists within the WebAssembly.Instance method, resulting from the lack of proper validation of user-supplied data. This can lead to a write past the end of a heap-based buffer, allowing an attacker to execute code in the context of the current process.

Recommendations For versions prior to 10.4.0, update to version 10.4.0 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially malicious web pages or files to minimize the risk of exploitation.
