An issue was discovered in Samsung Mobile Processor Exynos 1480, Exynos 2400. The xclipse amdgpu driver has a reference count bug. This can lead to a use after free.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
