There is a Memory Buffer Improper Operation Limit Vulnerability in Huawei Smartphone.Successful exploitation of this vulnerability may cause certain codes to be executed.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.

Affected Software

Name Vendor Start Version End Version
Emui Huawei 11.0.0 (including) 11.0.0 (including)
Magic_ui Huawei 4.0.0 (including) 4.0.0 (including)
