Description

An issue was discovered in Samsung Mobile Processor and Wearable Processor Exynos 850, Exynos 1080, Exynos 2100, Exynos 1280, Exynos 1380, Exynos 1330, Exynos W920, Exynos W930. The mobile processor lacks proper memory deallocation checking, which can result in a UAF (Use-After-Free) vulnerability.

• CWE-416Use After FreeThe 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
• CWE-762Mismatched Memory Management RoutinesThe product attempts to return a memory resource to the system, but it calls a release function that is not compatible with the function that was originally used to allocate that resource.
