CVE-2026-76061
Cri-o: cri-o: bind_mount_prefix intermediate-symlink prefix bypass
A flaw was found in CRI-O's bind_mount_prefix handling. When configured with a non-empty bind_mount_prefix, a malicious container or local attacker could use a Container Runtime Interface (CRI) hostPath containing an intermediate absolute symlink. This could cause the bind mount source to resolve outside the intended prefixed root, potentially leading to unauthorized access to files or privilege escalation on the host system.
