AI Analysis
Technical Summary
CVE-2025-13193 is an information disclosure vulnerability in libvirt affecting Red Hat Enterprise Linux 10. The flaw involves external inactive snapshots of shut-down virtual machines being created with incorrect default permissions that are world-readable. This allows users with limited privileges on the host to read the guest OS contents from these snapshots. The vulnerability is classified with a CVSS 3.1 base score of 5.5, indicating medium severity. The vendor advisory from Red Hat does not explicitly state the availability of a patch or mitigation steps.
Potential Impact
Unprivileged users on the host system can access sensitive data from guest virtual machines by reading world-readable external inactive snapshots. This compromises confidentiality but does not affect integrity or availability of the system or virtual machines.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2025-13193 for current remediation guidance. Until a fix is confirmed, restrict access to snapshot files and consider limiting unprivileged user permissions on the host to reduce exposure.
