CVE-2026-46113 KVM: x86: Fix shadow paging use-after-free due to unexpected GFN

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Fix shadow paging use-after-free due to unexpected GFN The shadow MMU computes GFNs for direct shadow pages using sp-gfn plus the SPTE index. This assumption breaks for shadow paging if the guest page tables are modifie...

The adjustments made for XSA-379 as well as those subsequently becoming XSA-387 still left a race window, when a HVM or PVH guest does a grant table version change from v2 to v1 in parallel with mapping the status pages via XENMEMaddtophysmap. Some of the status pages may then be freed while...

DEBIAN-CVE-2022-33747

Arm: unbounded memory consumption for 2nd-level page tables Certain actions require e.g. removing pages from a guest's P2M Physical-to-Machine mapping. When large pages are in use to map guest pages in the 2nd-stage page tables, such a removal operation may incur a memory allocation to replace a...
