Use-after-free vulnerability in the Samsung Exynos fimg2d driver for Android with Exynos 5433, 54xx, or 7420 chipsets allows attackers to obtain sensitive information via unspecified vectors. The Samsung ID is SVE-2016-6853.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
