Vulnerability in CRI-O's bind_mount_prefix handling (CVE-2026-76061)

Summary

Vulnerability in CRI-O's bind_mount_prefix handling (CVE-2026-76061). Risk of unauthorized operations or information disclosure. Exploitable via bind_mount_prefix.

Original description

The description as published by the source.

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.
