Issue:
In x86-64 architecture, particularly under Windows 10 and Windows 11, imported functions fail to correctly jump to the original execution flow after hooking.
Changes:
Added handling for the "0x48 0xff 0x25" instruction in the
hook_create_stubfunction to resolve the issue. This change ensures correct redirection to the original execution path after hooking imported functions.Testing:
Thoroughly tested on Windows 10 and Windows 11 environments to validate the fix's effectiveness and stability.
