  • Systems and methods for preventing unauthorized stack pivoting
    Patent number: 9239801
    Abstract: An example processing system may comprise: a lower stack bound register configured to store a first memory address, the first memory address identifying a lower bound of a memory addressable via a stack segment; an upper stack bound register configured to store a second memory address, the second memory address identifying an upper bound of the memory addressable via the stack segment; and a stack bounds checking logic configured to detect unauthorized stack pivoting, by comparing a memory address being accessed via the stack segment with at least one of the first memory address and the second memory address.

  • HARD DISK CACHING WITH AUTOMATED DISCOVERY OF CACHEABLE FILES
    Publication number: 20140344509
    Abstract: In some embodiments a permanent cache list of files not to be removed from a cache is determined in response to a user selection of an application to be added to the cache. The determination is made by adding a file to the cache list if the file is a static dependency of the application, or if a file has a high probability of being used in the future by the application. Other embodiments are described and claimed.
