The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0306-1 advisory. - CVE-2025-58150: Fixed buffer overrun with shadow paging and tracing XSA-477 bsc1256745 - CVE-2026-23553: Fixed incomplete IBPB for vCPU isolation...

CVE-2026-23553

In the context switch logic Xen attempts to skip an IBPB in the case of a vCPU returning to a CPU on which it was the previous vCPU to run. While safe for Xen's isolation between vCPUs, this prevents the guest kernel correctly isolating between tasks. Consider: 1 vCPU runs on CPU A, running task ...
