CVE-2026-76061 | BDVDB-2026-383213 Detail
Red HatRed Hat OpenShift Container Platform 4
Description#
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.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact low. Attack vector: network.
Weaknesses#
