CVE-2025-58147
CVE-2025-58147 and CVE-2025-58148 describe Xen hypervisor boundary-checking bugs in Viridian hypercalls. Affected: hypercalls using the HV_VP_SET Sparse format can cause vpmask_set() to write out of bounds when converting bitmaps; any input format can cause send_ipi() to read d->vcpu[] out-of-...

CVE-2025-58148
Xen hypervisor vulnerability CVE-2025-58148 arises from Viridian hypercalls accepting vCPU ID masks in any input format. The flaw can cause send_ipi() to read d->vcpu[] out-of-bounds and operate on a wild vCPU pointer, enabling out-of-bounds reads/writes. Connected advisories confirm impact on...
