In Android before security patch level 2018-04-05 on Qualcomm Snapdragon Mobile and Snapdragon Wear MSM8909W, SD 210/SD 212/SD 205, SD 450, SD 615/16/SD 415, SD 625, SD 650/52, SD 820, SD 835, SD 845, while the DPM native process is processing framework events, the iterator pointer is deleted after processing an event. When processing subsequent events, a Use After Condition will occur.

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
