Therefore, when a read request is received by VMM from the File System (FS) or ODM, VMM tries to copy the Kernel Input Output (KIO) buffer, created by VMM, to the user buffer. When VMM tries to write to the user buffer, which receives information from the FS or the ODM layer, the FS or the ODM layer that have the READ_ONLY permission cannot be written to VMM. This results in the panic. RESOLUTION: The code is modified such that the flags passed by ODM to the VMM layer are correct.
