high Nessus Plugin ID 326001

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-2026:2804-1 advisory.

- CVE-2026-9804: Symlink escape in the VMExport dir handler let an attacker controlling an exported PVC read sensitive files (TLS keys, tokens, service-account creds) from the exporter pod. (bsc#1266733)
- CVE-2025-14525: A VM reporting many guest-internal interfaces via the guest agent could flood VMI status and fill etcd (denial of service). Caps reported interfaces at 10. (bsc#1256434)
- CVE-2026-35469: resource-exhaustion in the SPDY/3 protocol implementation of github.com/moby/spdystream. (GHSA-pc3f-x583-g7j2,bsc#1262265)

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.
