Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:4330-1 advisory.

Updated kubevirt to version 1.6.3:

- CVE-2025-22872: Fixed incorrect interpretation of tags leading content to be placed wrong scope during DOM construction in golang.org/x/net/html (bsc#1241772)
- CVE-2025-64432: Fixed bypass of RBAC controls due to incorrect validation of certain fields in the client TLS certificate (bsc#1253181)
- CVE-2025-64433: Fixed arbitrary files read via improper symlink handling (bsc#1253185)
- CVE-2025-64434: Fixed privilege escalation via virt-api impersonification due to compromise virt- handler instance (bsc#1253186)
- CVE-2025-64437: Fixed mishandling of symlinks (bsc#1253194)
- CVE-2025-64324: Fixed a logic bug that allows an attacker to read and write arbitrary files owned by more privileged users (bsc#1253748)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kubevirt-manifests and / or kubevirt-virtctl packages.
