How to Fix CVE-2022-0532

To remediate this vulnerability, upgrade all affected Github.com/cri o/cri o dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/cri-o/cri-o fixed: 1.23.1 
Upgrade github.com/cri-o/cri-o to 1.23.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/cri-o/cri-o

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-0532, inspect your project dependencies for Github.com/cri o/cri o:

inspect dependencies for github.com/cri-o/cri-o

Analyze the terminal output to locate any version of Github.com/cri o/cri o in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.23.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-732: Incorrect Permission Assignment for Critical Resource, where the product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. In Github.com/cri o/cri o, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace.
