CVE-2021-43310
A vulnerability in Keylime before 6.3.0 allows an attacker to craft a request to the agent that resets the U and V keys as if the agent were being re-added to a verifier.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.21%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
