What is CVE-2022-1708?

A crucial issue in CRI-O allows users with access to the Kube API to exploit ExecSync requests, leading to potential memory or disk space exhaustion on the node. When commands are executed within a container, their outputs can become excessively large, causing CRI-O to consume significant system resources when reading this data. This vulnerability places system availability at risk, making it imperative for organizations to apply the necessary updates to protect their infrastructure.

CRI-O Affects cri-o <= 1.24.0, 1.23.2, 1.22.4, Fixed-in 1.24.1, 1.23.3, 1.22.5
