AMD announced that it has fixed a rather substantial list of vulnerabilities in the drivers for Windows 10 and 11 of its Radeon video cards: none of these had, fortunately, a critical threat level, but 18 were classified as high priority and the remaining 9 medium. Overall, the vulnerabilities exposed systems to various types of attacks, including escalation of privilege, denial of service (DoS), sensitive information theft, write permission to kernel memory and bypass of Kernel Address Space Layout Randomization (KASLR).
The fixes were released months ago: the latest ones were part of driver 21.4.1, released in mid-April, which also contained a lot of functional innovations, an all-new graphical interface of the Radeon software, significant improvements from AMD Link and ReLive customers, support a Variable Rate Shading (VRS) in several titles and even a series of optimizations that have significantly reduced the power consumption of the Radeon RX 6000 GPUs, especially when idle or when playing multimedia content.

Radeon Software Adrenalin 21.11.2 is now available, with Day-0 Driver support for Battlefield 2042 – with up to 15% increase in performance @ 4K Ultra Settings.

Interestingly, these bugs are the reason that prompted Intel to release a new driver for its Kaby Lake-G processors with integrated Radeon GPU, even though support was formally already terminated. The 21.10.03.11 drivers for Kaby Lake-G arrived in mid-September.
We take this opportunity to report that in recent days AMD has also released a new version of its Adrenalin drivers, 21.11.2. The main novelty is the support for the brand new Battlefield 2042, released that day: performance improvements between 11 and 15% are reported with the latest generation of Radeon RX 6000 GPUs. Staying on the security side, AMD said it had resolved a total of 22 vulnerabilities in its EPYC server processors, four of which were high-threat (the rest were medium-level).
