Abstract
In general, the invention is directed to techniques for identifying memory overruns. For example, as described herein, a device includes a main memory that enables an addressable memory space for the device. A plurality of memory pages each comprises a separate, contiguous block of addressable memory locations within the addressable memory space. The device also includes a memory manager comprising a secure pool allocator that assigns a secure pool size value to a first one of the plurality of memory pages. The secure pool size value defines a plurality of protected memory spaces in the first memory page that partition the first memory page into a plurality of secure objects. The device also includes a memory management unit comprising secure pool logic that determines, based on the secure pool size value, whether a memory address is an address of one of the protected memory spaces in the first memory page.
