CVE-2026-79603

x86 PV guests can free memory pages while still keeping a stale TLB entry pointing to them. A TLB flush is only issued by Xen if needed when the page is re-used. Since it's possible for the page to be scrubbed ahead of the TLB flush, there's a window where a PV guest can modify an already scrubbe...

CVE-2026-79603

Xen hypervisor x86 PV (para-virtualized) guests can free memory pages while retaining a stale TLB entry pointing to them. Xen issues a TLB flush only when a freed page is re-used , not at the time of freeing. Because the page can be scrubbed (zeroed or reassigned) before that TLB flush occurs, a ...

CVE-2026-62437

CVE-2026-62437 is a memory leak vulnerability in the Xen hypervisor's x86 device model (DM) path. During guest termination, PCI device cleanup removes IRQ tracking structures early in the process, but the guest's DM can subsequently re-establish those structures by re-binding IRQs , leaving at le...
