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.

In the Linux kernel, the following vulnerability has been resolved:
x86/amd_node: Avoid divide by zero on virtualized systems
On a virtualized system, the number of nodes does not have a relationship to the number of roots. A Xen PVH dom0 can calculate roots_per_node as 0, which crashes with a divide by zero in:
if (count++ % roots_per_node)
because the underlying topology code on Xen ends up making num_nodes 2 and num_roots 1 and the integer division result is 0.
The issue is seen with Xen, but it could affect other systems.
Set roots_per_node to 1 in this case. Print a firmware bug when this is performed for non-virtualized systems.
