FIX: Drivers That Have Images That Are Larger Than 16 Megabytes May Corrupt Memory When Loaded (827484)


The information in this article applies to:

  • Microsoft Windows XP Professional
  • Microsoft Windows XP Professional SP1
  • Microsoft Windows Server 2003, Standard Edition

SYMPTOMS

When you load drivers that have images that are larger than 16 megabytes (MB), or when you load drivers that declare very large static arrays, an error message may appear on a blue screen when the system tries to load the drivers.

The information in the error message (on the blue screen) reveals that the system is reading past the end of a pool allocation. This condition is evidenced by page table entry (PTE) allocations that are not valid.

WORKAROUND

To work around this problem, reduce the size of the driver image by replacing large static arrays with dynamically allocated arrays.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.
