Confidential Compute Attestation
Monthly
Privilege escalation in CRI-O (the OCI container runtime used by Red Hat OpenShift Container Platform 4 and many Kubernetes clusters) lets an attacker who can set container environment variables inject a newline into the HOME variable and append arbitrary lines to /etc/passwd, enabling creation of a rootful or otherwise privileged account inside the container. It is a bypass of the incomplete fix for CVE-2022-4318, whose HOME sanitization was insufficient. No public exploit identified at time of analysis and it is not listed in CISA KEV.
