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.

relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
net: do not delay dst_entries_add() in dst_release()
dst_entries_add() uses per-cpu data that might be freed at netns dismantle from ip6_route_net_exit() calling dst_entries_destroy()
Before ip6_route_net_exit() can be called, we release all the dsts associated with this netns, via calls to dst_release(), which waits an rcu grace period before calling dst_destroy()
dst_entries_add() use in dst_destroy() is racy, because dst_entries_destroy() could have been called already.
Decrementing the number of dsts must happen sooner.
Notes:
in CONFIG_XFRM case, dst_destroy() can call dst_release_immediate(child), this might also cause UAF if the child does not have DST_NOCOUNT set. IPSEC maintainers might take a look and see how to address this.
There is also discussion about removing this count of dst, which might happen in future kernels.
