Systems, methods, and computer storage mediums are provided for mitigating damage to data caused by a computer process having a corrupted pointer. An exemplary method includes receiving a pointer to a memory address. The pointer is received in conjunction with a command of the computer process to access data stored at the memory address, where the data is intended to be stored in a memory segment that allows for read-only access. The memory segment that includes the memory address is analyzed to determine a modification state for the memory segment, where the modification state indicates the type of access that the memory segment allows. The computer process is halted when the modification state indicates that the memory segment allows for other than read-only access.
