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.

In the Linux kernel, the following vulnerability has been resolved:
nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error
The nouveau_dmem_copy_one
function ensures that the copy push command is
sent to the device firmware but does not track whether it was executed
successfully.
In the case of a copy error (e.g., firmware or hardware failure), the
copy push command will be sent via the firmware channel, and
nouveau_dmem_copy_one
will likely report success, leading to the
migrate_to_ram
function returning a dirty HIGH_USER page to the user.
This can result in a security vulnerability, as a HIGH_USER page that may contain sensitive or corrupted data could be returned to the user.
To prevent this vulnerability, we allocate a zero page. Thus, in case of an error, a non-dirty (zero) page will be returned to the user.
