Intel has disabled DirectX 12 assist on its 4th technology Haswell processors with onboard graphics thanks to a stability vulnerability. The vulnerability may possibly let escalation of privilege, or in other words and phrases, enable an unauthorized person to execute undesired actions.
It would feel to be a rather drastic action to disable DirectX 12 support entirely, somewhat than difficulty an up to date driver or patch, so it will be appealing to see if Intel will make further more remark on the particulars of the vulnerability, or no matter whether it has the probable to be exploited on other CPU generations.
Starting off with driver 18.104.22.16807, the disabled CPUs are those with Iris Professional 5200, Iris 5100, High definition 5000, 4600, 4400 and 4200 graphics, along with 4th Technology Pentium and Celeron products. Additionally, in accordance to Tom’s Hardware, 4th Generation Ivy Bridge processors with the same Gen 7 GPU architecture are seemingly unaffected, at minimum for now.
Nevertheless most enthusiast gamers have moved on from Haswell processors, there are no question lots of 4000 sequence CPUs chugging together in desktops and significantly laptops worldwide. Customers that do use the Hd and Iris graphics of the time are not way too very likely to be jogging significantly DX12 articles anyway so this may possibly convert out be something of a almost nothing burger.
However, it’s a bit of a black eye for Intel which has acquired some poor PR in latest decades above stability concerns, notably the Spectre and Meltdown vulnerabilities.
In the meantime, Intel suggests that end users downgrade the driver to edition 22.214.171.12463 or older in order to operate Immediate X 12 content material, and if Intel is inclined to suggest that, possibly the difficulty is not all that severe at all.
