| Doc Text: |
A flaw was found in Kyverno. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by exhausting system memory. By supplying specially crafted, highly compressed attestation layers in container registry artifacts, an attacker triggers unbounded decompression within the admission controller. This leads to excessive memory consumption, causing the controller process to crash and disrupting admission control operations.
