CVE-2026-46113

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine x86 shadow paging mechanism. This use-after-free vulnerability arises from incorrect handling of Guest Frame Numbers GFNs when guest page tables are modified. A local attacker with control over a guest virtual machine could...

EUVD-2026-32872

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...

CVE-2025-68743

The CVE-2025-68743 entry concerns the Linux kernel: the mshv memory-region creation check was incorrect and could mis-handle regions that start before and end after existing regions. The fix replaces the flawed beginning/end overlap checks with a proper range intersection check against gfns and u...
