A vulnerability was found in Moby (Docker Engine) where containers were started incorrectly with non-empty inheritable Linux process capabilities.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
