Kerentanan Improper Link Resolution Before File Access ('Link Following'). Skor CVSS 3.1 5.5 (Medium) menurut redhat.com.

Deskripsi (NVD)

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.
