CVE-2026-42493 in Xen
Tóm tắt
Bởi MITRE • 28/07/2026
Addressing certain issues, in particular related to operations which may take excessively long and therefore would need preemption, has turned out overly costly. Since alternatives (HVM/PVH: HAP, PV: shim) are commonly available, the decision was to deprecate the functionality, while still retaining it for people to use at their own (security) risk. Memory-wise small enough guests may still be okay to run.
Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
