A system and method in one embodiment includes modules for detecting an access attempt to a critical address space (CAS) of a guest operating system (OS) that has implemented address space layout randomization in a hypervisor environment, identifying…

A system and method for address space layout randomization ("ASLR") for a Windows operating system is disclosed. The address space layout includes one or more memory regions that are identified and then a particular implementation of the system…

The present application relates generally to laying out address space for execute-in-place code and, more specifically, to a method for address space layout randomization for such code. Ahead of executing a program, executable code for which is store…

FIELD OF THE INVENTION The present invention is related to computing systems, and more particularly to a system and method for adjusting to changes in processor performance. BACKGROUND INFORMATION Designers of mobile computing platforms are faced wit…

BACKGROUND INFORMATION An embodiment of the present invention relates generally to virtualization platforms and, more specifically, to a system and method to run components of a virtual machine monitor at a reduced privilege level. Various mechanisms…

The prioritization of large memory page mapping is a function of the access bits in the L1 page table. In a first phase of operation, the number of set access bits in each of the L1 page tables is counted periodically and a current count value is cal…

Virtual addresses from multiple address spaces are translated to real addresses in main memory by generating for each virtual address an address space identifier (AID) identifying its address space. Then, the virtual address and its AID are used to o…

http://thinkiii.blogspot.jp/2014/02/arm32-linux-kernel-virtual-address-space.html   The 32-bit ARM CPU can address up to 2^32 = 4GB address*. It's not big enough in present days, since the size of available DRAM on computing devices is growing fast a…

Memory Layout (Virtual address space of a C process) 分类: C语言基础2012-12-06 23:16 2174人阅读 评论(0) 收藏 举报 found a good example to demostrate the memory layout and its stack info of a user-mode process, only that this example is for Linux. But it is still wo…

Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. In order to prevent an attacker from reliably jumping to, for example, a particular exploited functio…
