Intel disables DirectX 12 on older processors due to security vulnerability

Intel has disabled DirectX 12 API support in the latest graphics drivers for its Haswell processors due to a security vulnerability.

Intel has disabled DirectX 12 API support in the latest graphics drivers for its 4th generation Core processors due to a security vulnerability. Codenamed ‘Haswell’, the fourth-generation Core processors were originally released in 2013 as successors to the company’s Ivy Bridge CPUs released in 2012. Haswell processors are getting a bit longer, but remain in circulation as long as possible. on desktops and laptops all over the world.

News of the latest security flaw comes at a time when Intel has yet to fully recover from the impact of the Specter and Meltdown vulnerabilities that were originally detailed in 2018 and affected several generations of the company’s processors. Earlier this year, researchers found a new load value injection threat affecting Intel CPUs. Based on Meltdown and Specter, the exploit exploits a flaw in the speculative execution of modern processors.

Intel has Announced that you are disabling DX 12 support in your latest graphics drivers for Haswell processors due to a security vulnerability that could allow privilege escalation on these CPUs. To mitigate the issue, the company released a software update that would disable DX 12 support on these chips for driver version This means that people who use the integrated graphics in these processors will not be able to run DX 12 applications if they have the latest drivers installed. Intel recommends users downgrade to driver version or earlier if they want to run DirectX 12 applications on the integrated GPUs of their Haswell systems.

Non-Haswell processors are not affected

Chips affected by the vulnerability include 4th generation Core processors with Intel Iris Pro Graphics 5200, Iris Graphics 5100, and Intel HD Graphics 5000/4600/4400/4200. Intel Pentium and Celeron processors with 4th generation Intel Core-based Intel HD Graphics are also affected by the flaw, the company said. As pointed out Hardware de Tom, all affected GPUs are based on Intel’s Gen7 architecture, but none of the Ivy Bridge chips appear to be affected by the issue, although the same architecture is used in those chips as well.

Even as Intel is plugging in security vulnerabilities in its old processors, the company is busy releasing new processors to the enthusiast market. At the end of last month, Intel released its Alder Lake CPUs that include the top-of-the-line Core i9-12900K, which will be the successor to the Core i9-11900K released earlier this year. The company is also preparing its next Arc Alchemist GPU line that will launch early next year and is expected to offer the first real competition to NVIDIA and AMD.
