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 a few clicks we can analyze your entire application and see what components are vulnerable in your application, and suggest you quick fixes.

In the Linux kernel, the following vulnerability has been resolved:
net/sched: fq_pie: prevent dismantle issue
For some reason, fq_pie_destroy() did not copy working code from pie_destroy() and other qdiscs, thus causing elusive bug.
Before calling del_timer_sync(&q->adapt_timer), we need to ensure timer will not rearm itself.
