Abstract
Technologies for identification of a potential root cause of a use-after-free memory corruption bug of a program include a computing device to replay execution of the execution of the program based on an execution log of the program. The execution log comprises an ordered set of executed instructions of the program that resulted in the use-after-free memory corruption bug. The computing device compares a use-after-free memory address access of the program to a memory address associated with an occurrence of the use-after-free memory corruption bug in response to detecting the use-after-free memory address access and records the use-after-free memory address access of the program as a candidate for a root cause of the use-after-free memory corruption bug to a candidate list in response to detecting a match between the use-after-free memory address access of the program and the memory address associated with the occurrence of the use-after-free memory corruption bug.
