Security of Intel Graphics (HD4600) on 4th Gen Core i7 (Braswell)

Jump to solution

Running on:

  • Windows 10 Pro, 64bit, build 18358.1
  • Intel Core i7 4770S (4th generation, aka Braswell)
  • Intel HD 4600 on motherboard (1st display for desktop)
  • nVidia graphics on PCIExpress x16 (2nd display for graphis intensive applications)

The security advisory says that all Graphics drivers should be updated to be at a minimum version.

See

https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00189.html

 

However for Intel HD 4600 (on Intel Core i7 4th Generation [4770S]) the LATEST driver (for Windows 10) listed is:

"Intel® Graphics Driver for Braswell, 4th and 5th generations. (15.40.41.5058)", dated 9/18/2018 (so before the CVE security report, and before the Intel advisory report).

https://downloadcenter.intel.com/download/28163/Intel-Graphics-Driver-for-Windows-15-40-?product=809...

 

Both your reports say that ALL Graphics drivers on iCore processors are affected.

 

But you instruct users to update with a graphics drivers that is not even available (and is still below the minimum version needed to match the advisory).

 

So are users of Intel Core processors (i3 to i7) of 4th and 5th generations ("Core iN-4NNN*" or "Core iN-5NNNN*") really immune to these bugs ? If so Intel should review its own advisory.

That's a Haswell processor, BTW. 😜

Yes for my processor, but what I posted was the description of the driver (as seen on the Intel site) that was then available and already installed on my system.

When I asked this question, there was no other driver listed (including by using the "automatic update" to scan my system, it was still that version, at the link I posted.

Now the page at that link displays (only since today) that a newer version is available at the link you gave).

So the advisory was posted, drivers were made according to it, but not all of them were published and made available for download. This is done now, thanks for your attention.

This driver is now rejected in Windows 10 (won't load at all in Secure UEFI boot, because untrusted use of memory transfers).

I just see the PC OEM logo appearing during boot, and windows starts loading on it, then the "rotating dots" freeze on the screen, and Windows 10 disables the device which is then reported with a problem in the drivers named "igfx.sys" with unauthorized memory accesses.

 

The windows device manager reports a problem code 48 : contact the manufacturer to get a new driver.

I tried uninstalling that drivers completely, reboot, and then Windows attempts to use a generic VGA software driver, which also fails.

No resources at all (memory maps interrupts, DMA channels...) are given to the device which displays a yellow /!\ sign.

The installation of drivers are still marked successful (result 0), but the drivers are definitely not allowed to load in secure boot and Windows cannot even map basic resources itself for the device.

All I can do to get some display is to plug an addon display board on the PCI express slot, but then I have only one screen available (only one HDMI port and 3 Display ports), which works, but I can no longer plug my TV. The Intel HD4600 is now unusable (except in Bios or in early boot time where there's a basic display, not supported at all in Windows 10 after boot (the display from the Intel board remains frozen with the Gigabyte BIOS logo and a few frozen dots on a black background).

For info here is the content of C:\Intel\Logs\IntelGFXCoin.log
