CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

A local attacker running as the confined swtpm user could exploit a symlink-following vulnerability in libvirt's virFileChownFiles() function to trick the root-level libvirt daemon into changing the ownership of an arbitrary file. The vulnerability allows for privilege escalation from the swtpm sandbox to root-level file ownership control. Affected versions are not specified.

Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

If virtual Trusted Platform Module (vTPM) functionality is not required, remove the <tpm> device definition from the domain XML configuration to prevent the vulnerable code path from being reached.

To check if a domain uses vTPM:

virsh dumpxml <domain> | grep -A5 '<tpm'

To remove it, edit the domain XML and delete the <tpm> block. This prevents libvirt from spawning swtpm processes and from calling virFileChownFiles() on the swtpm state directory during domain startup. Domains that require vTPM for guest OS functionality cannot use this mitigation and should prioritize applying the upstream fix.

Original source description

Read the full publisher description

A flaw was found in libvirt. A local attacker, specifically a process running as the confined swtpm user, could exploit a symlink-following vulnerability in the virFileChownFiles() function. By planting a symbolic link within the swtpm state directory, the attacker could trick the root-level libvirt daemon into changing the ownership of an arbitrary file to the swtpm user. This allows for privilege escalation from the swtpm sandbox to root-level file ownership control.
