Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

NewCVE-2026-90286 (opens in a new tab)How to fix?
Upgrade Debian:12 linux-6.12 to version 6.12.111-1~deb12u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream linux-6.12 package and not the linux-6.12 package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/gfx6: Use PFP on the compute queues too
On GFX6, the compute rings use the same CP path as the graphics ring. The only difference is that they don't support draw commands. (As opposed to GFX7 and newer which have a separate command parser that is called MEC for compute queues.)
This means that we have to take into consideration that the PFP also exists on compute queues on GFX6:
Use PFP for register writes on both graphics and compute queues.
In the pipeline sync, use the PFP to wait for the previous fence (and not the ME) to prevent the PFP from starting to execute the next submission while the ME is still in the previous submission.
After a VM flush, emit PFP_SYNC_ME on compute queues as well.
