In all android releases(Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, Un-trusted pointer de-reference issue by accessing a variable which is already freed.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
