Not all drivers communicate directly with a device. Often, several drivers layered in a driver stack take part in an I/O request. The conventional way to visualize the stack is with the first participant at the top and the last participant at the bottom, as shown in this diagram. Some drivers in the stack change the request from one format to another. These drivers don't communicate directly with the device. Instead, they change the request and pass it to drivers that are lower in the stack.
Some filter drivers observe and record information about I/O requests but don't actively take part in them. For example, some filter drivers act as verifiers to make sure the other drivers in the stack handle the I/O request correctly.
Software drivers always run in kernel mode. They're primarily written to access protected data only available in kernel mode. However, not all device drivers need access to kernel-mode data and resources, so some device drivers run in user mode.
I have seen this a couple of times. I generally recommend to NOT update virtual machine tools drivers via Windows Update, this has to be a controlled process. You can configure a group policy/registry setting, to prevent drivers from Windows Update/WSUS.
Here you can download drivers for DisplayLink USB graphics chipsets incorporated in your dock, adapter or monitor. We recommend to update to the latest driver to address any potential security issue, fix bugs, improve performance and add new features.
For DS4/DS5 to properly function on your Windows 10/11 PC you are required to install necessary first and third party drivers. Some of which, of course, are optional but will improve DS4windows capabilities. Here we will list and give a description of every driver needed to allow your DualShock 4 and DualSense 5 to work. Launching the DS4 app will also ask to install the drivers.
In information security, even seemingly insignificant issues could pose a significant threat. One notable vector of attack is through device drivers used by legitimate software developers. There are numerous available drivers to support legacy hardware in every industry, some of which are from businesses that have long stopped supporting the device. To continue operations, organizations rely upon these deprecated device drivers.
This creates a unique attack vector, as Microsoft Windows allows loading kernel drivers with signatures whose certificates are expired or revoked. This policy facilitates threat actors to disable security software functions or install bootkits using known vulnerable drivers. Since the Windows 11 2022 update, the vulnerable drivers are blocked by default using Hypervisor-Protected Code Integrity (HVCI). However, this banned-list approach is only effective if the vulnerable driver is known in advance.
The Carbon Black Threat Analysis Unit (TAU) discovered 34 unique vulnerable drivers (237 file hashes) accepting firmware access. Six allow kernel memory access. All give full control of the devices to non-admin users. By exploiting the vulnerable drivers, an attacker without the system privilege may erase/alter firmware, and/or elevate privileges. As of the time of writing in October 2023, the filenames of the vulnerable drivers have not been made public until now.
Previous research such as ScrewedDrivers and POPKORN utilized symbolic execution for automating the discovery of vulnerable drivers. As far as TAU researched, symbolic execution (or the specific implementations based on angr) fails at an unignorable rate by causing path explosions, false negatives and other unknown errors.
TAU automated the hunting process of vulnerable WDM/WDF drivers by using an IDAPython script. IDAPython is the Python programming language to access APIs of IDA Pro (hereinafter called IDA), which is a commercial disassembler widely used by reverse engineers. The script implementation is based on the Hex-Rays Decompiler SDK and will be detailed in the next section below.
The IDAPython script has two functions: triage and analysis. The triage function robustly detects potentially vulnerable drivers from large sets of samples in IDA batch mode (command-line interface) execution. After the triage, we need to confirm that the detected drivers are truly vulnerable on IDA GUI. The analysis function substantially assists the tedious manual validation.
The IOCTL handler identification method depends on the driver type. In WDM drivers, the triage function code simply detects an assignment to the MajorFunction array member of the DRIVER_OBJECT structure then applies the function type. On the other hand, the method for WDF drivers requires a multiple-step procedure.
Moreover, WDF drivers built with debug information, or some older drivers, create function wrappers when calling WDF APIs. In that case, the script detects the wrappers and sets their function types then traces back assignments to the arguments in the parent functions.
The script handles WDF drivers in the same way, but it additionally sets argument names and types of the following WDF APIs handling user data I/O since IDA does not support WDF type information by default.
Next, TAU de-duplicated the samples based on imphash then executed the IDAPython script for the imphash-unique samples in batch mode. The extracted samples were about 300 WDM drivers and 50 WDF. Among them, TAU excluded drivers with the following conditions.
Those drivers are not vulnerable in terms of access control, though privileged attackers can still abuse them as the Bring Your Own Vulnerable Driver (BYOVD) techniques by loading and exploiting the drivers for their purposes like disabling security software.
Finally, TAU discovered 34 vulnerable drivers (30 WDM, 4 WDF) with firmware access, including ones made by major chip/BIOS/PC makers. This is the number based on the unique filenames. Practically, there are 237 file hashes in the wild. All discovered drivers give full control of the devices to non-admin users. TAU could load them all on HVCI-enabled Windows 11 except five drivers.
As shown in Figure 16, four drivers require to send multiple IOCTL requests for the memory mapped I/O operations above. On the other hand, two drivers (IoAccess.sys and phymem_ext64.sys) return a user-mode address pointer mapping the SPI registers in the output buffer, so a single IOCTL request is enough to erase firmware.
The EoP PoCs (eop_*.py) were implemented for the three drivers included in Table 2. They are classic token stealing exploits that read a token value of the System process in the _EPROCESS structure and write the value into the field of the Python exploit process. In Figure 19 below, a non-privileged user could run cmd.exe with system integrity level by the exploit on HVCI-enabled Windows 11.
Two drivers allow arbitrary virtual memory access directly for EoP. Another driver (stdcdrvws64.sys) demands two IOCTL requests per access to translate a virtual address to a physical one by MmGetPhysicalAddress then read/write data at the physical address through arbitrary memory mapped I/O.
In April and May 2023, TAU reported the vulnerabilities to the vendors whose drivers had valid signatures at the time of discovery. Only two vendors fixed the vulnerabilities and the following CVEs were assigned.
By implementing the static analysis automation script, TAU discovered 34 unique vulnerable drivers (237 file hashes) that were not recognized previously. WDM drivers are still widely used, but we can also discover and exploit vulnerable WDF drivers in a similar fashion.
While a lot of vulnerable drivers have been reported by researchers, TAU found not only old vulnerable drivers but also new ones with valid signatures. It seems likely that we need more comprehensive approaches in the future than the current banned-list method used by Microsoft. For example, a simple prevention of loading drivers signed by revoked certificates will block about one-third of the vulnerable drivers disclosed in this research.
VirtIO Drivers are paravirtualized drivers for kvm/Linux (see -kvm.org/page/Virtio). In short, they enable direct (paravirtualized) access to devices and peripherals for virtual machines using them, instead of slower, emulated, ones.
A quite extended explanation about VirtIO drivers can be found here -virtio.

This package contains the configuration files for all Total Phase devices. Refer to README.txt and the user manual for more details on how the Total Phase devices use the built-in USB drivers in Linux. We support Red Hat, SuSE, Ubuntu, Fedora.
Windows:
The Windows installer contains the 32-bit and 64-bit USB drivers. The drivers support Windows 7 through 11.
I dual booted my computer into my other OS (32 bit Vista) which I keep just for test purposes. Everything
installs and functions properly, including the USB drivers, the SW works and recognizes the
TLV320DAC32EVM-PDK.
The USB drivers for the composite device and the USB audio device are correctly loaded since they are part of the Windows 7 OS. In fact I can stream audio to the DAC if it is initialized from a separate system. But the NI-VISA USB driver is required to enable the EVM SW to communicate with the EVM-PDK to control the DAC registers through the EVM GUI.
This board was designed to work with XP which was the dominant system in use when this chip was released. Our newer devices are being designed to operate on Windows 7 and no longer use NI drivers. We do not have the resources to go back and re-design all of our old software for older EVM's. We typically stop supporting old EVM's once the chip is established in the market. Our limited resources are focused on designing new boards and software for new parts.
