Granted, Red Hat Enterprise Linux is largely used on servers where graphics aren't utilized but this would also lose out on any OpenCL support and yes generally cause a loss in power savings and not to mention hurt those running RHEL on workstations with Intel graphics.

Yet they suggest blacklisting the Intel graphics kernel driver while acknowledging " the power management functionality of the card will be disabled and the system may draw additional power.This mitigation may not be suitable if the graphical login functionality is required."īy disabling the Intel kernel graphics driver you lose out on hardware acceleration entirely as well as kernel mode-setting, which generally means running at a very low VESA resolution and the other display kinks that generally come with that experience.
INTEL GRAPHICS INSTALLER FOR LINUX PATCH
There's been the Gen9 patch already mainlined, Gen8 is protected by previous work, and the hard-hitting Gen7 is what's available in patch form. What's interesting about Red Hat's customer guidance is that they are recommending the disabling of Intel's kernel graphics driver (i915) as the mitigation to the issue. We're certainly learning more about this attack vector as details become available.

In particular, here is the explanation of how this vulnerability works based upon their information:ģ - ioctl issues it as an "Execution Unit" for the hardware.Ĥ - The kernel schedules another process to run.ĥ- Another process (running as user) can access the previous Execution Unit results by re-using Execution Units results.With interfacing with the kernel driver interfaces as opposed to finding some way to be nefarious through OpenGL/GLSL does at least make it sound like this exploit isn't possible through WebGL (as some have been concerned over due to Intel's lack of public information at the moment) but indeed would have to be local code run on the system directly. This Red Hat bug report does shed some more light onto the issue. Red Hat rates this CVE as having moderate impact. The contents of CVE-2019-14615 are still marked private, but the Red Hat Customer Portal has opened their guidance on this graphics flaw. Besides the Core i7 tests published yesterday in the aforelinked article, tests on relevant Core i3 and i5 CPUs are currently being carried out for seeing the impact there (so far, it's looking to be equally brutal). the Intel graphics hardware issue where for Gen9 all turned out to be okay but for Gen7 graphics leads to some big performance hits. */ - hw->phy.multispeed_fiber = false + hw->phy.It's been another day testing and investigating CVE-2019-14615, a.k.a. */ - hw->phy.multispeed_fiber = false + hw->phy.multispeed_fiber = true if (((comp_codes_1g & IXGBE_SFF_1GBASESX_CAPABLE) & (comp_codes_10g & IXGBE_SFF_10GBASESR_CAPABLE)) || ((comp_codes_1g & IXGBE_SFF_1GBASELX_CAPABLE) & -1771,7 +1771,7 s32 ixgbe_identify_qsfp_module_generic(struct ixgbe_hw *hw) hw->phy.sfp_setup_needed = true /* Determine if the QSFP+ PHY is dual speed or not.

For example: #define UBUNTU_VERSION_CODE (((LINUX_VERSION_CODE & ~0xFF) 255 #error UTS_UBUNTU_RELEASE_ABI is too large. Just in case you missed the point of vendor supplied drivers.
This is not the way to sell hardware, kids. So this driver compile shts itself if every planet isn't aligned with one guy using redhat in a dungeon at intel. They are hard coding kernel versions that they happen to use, rather than compile depending on whatever kernel build source it's being built on(the point of building from src in the first place). This driver is cancer on Debian/Ubuntu/Mint/Whatever.
