CVE-2022-42327

x86: unintended memory sharing between guests On Intel systems that support the "virtualize APIC accesses" feature, a guest can read and write the global shared xAPIC page by moving the local APIC out of xAPIC mode. Access to this shared page bypasses the expected isolation that should exist...

CVE-2022-42315

CVE-2022-42315 pertains to Xenstore in the Xen hypervisor. The issue is that malicious guests can cause xenstored to allocate large amounts of memory, leading to a DoS. The documented vectors include: issuing requests without reading responses (buffered in memory), generating many watch events, c...

CVE-2022-42322

CVE-2022-42322 concerns Xenstore: cooperating guests can create an arbitrary number of Xenstore nodes. The issue arises after the XSA-322 fix, where any Xenstore node owned by a removed domain can be reassigned to Dom0. A malicious pair of guests can exploit this by: (1) host A lets host B write ...

CVE-2022-42323

CVE-2022-42323 concerns Xenstore in the Xen hypervisor. The issue arises after the XSA-322 fix: any Xenstore node owned by a removed domain is reassigned to Dom0, enabling two cooperating guests to create an unbounded number of Xenstore nodes. This can exhaust Xenstore quota and lead to denial of...
