The Free On-line Dictionary of Computing (19 January 2023):

hole

   1.  In the hole model of current flow, the absence
   of an electron, e.g. in a semiconductor material.  In the
   electron model, a hole can be thought of as an incomplete outer
   electron shell in a doping substance.  Considering holes as
   positive charge carriers is a useful abstraction.

   2.  A security vulnerability, particularly one which
   allows an attacker to gain unauthorised access to a system (by
   analogy with a hole in a wall).

The Jargon File (version 4.4.7, 29 Dec 2003):

hole
 n.

    A region in an otherwise flat entity which is not actually present. For
    example, some Unix filesystems can store large files with holes so that
    unused regions of the file are never actually stored on disk. (In
    techspeak, these are referred to as ‘sparse’ files.) As another example,
    the region of memory in IBM PCs reserved for memory-mapped I/O devices
    which may not actually be present is called ‘the I/O hole’, since
    memory-management systems must skip over this area when filling user
    requests for memory.
