In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile MDM9615, MDM9625, MDM9635M, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 615/16/SD 415, SD 800, SD 808, and SD 810, use after free vulnerability when the PDN throttle info block is freed without clearing the corresponding active timer.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
