High [CVE-2025-9566] Podman: podman kube play command may overwrite host files

There's a vulnerability in podman where an attacker may use the kube play command to overwrite host files when the kube file container a Secrete or a ConfigMap volume mount and such volume contains a symbolic link to a host file path.

In a successful attack, the attacker can only control the target file to be overwritten but not the content to be written into the file. Binary-Affected: podman Upstream-version-introduced: v4.0.0 Upstream-version-fixed: v5.6.1 The Red Hat Product Security team has evaluated this vulnerability as having the Important severity.

This happens because of the consequences of an successful attack and the low complexity (AC:L) on exploiting this vulnerability.

Although the attacker cannot control the content written to the target file, depending on which file was targeted, the exploitation of this flaw may lead sensitive data corruption (I:H) and leading the system to crash resulting in a Denial of Service attack (A:H). Weakness: CWE-22.
