CVE-2026-104795 Insights-runtime-extractor: insights-runtime-extractor: container escape via privileged binary execution

The insights-runtime-extractor runs as a privileged DaemonSet hostPID: true that scans container processes for runtime fingerprinting. When scanning a container, the coordinator: 1. forks a child process 2. setns into the target container's PID and mount namespaces 3. fchdir back to an orphaned F...

CVE-2026-104795

The insights-runtime-extractor DaemonSet is vulnerable to a container escape due to insufficient privilege dropping during runtime fingerprinting. The coordinator uses seteuid() to switch users, but it fails to change the real UID (ruid) or saved-set-UID , which remain at 0 . Furthermore, the sec...
