HIGH 7.7EPSS 0.45%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
rkt through version 1.30.0 does not isolate processes in containers that are run with `rkt enter`. Processes run with `rkt enter` are not limited by cgroups during stage 2 (the actual environment in which the applications run). Compromised containers could exploit this flaw to access host resources.
