CVE-2026-98164

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Check write tracking in all address spaces kvmgfniswritetracked checks only the supplied memslot, but page tracking is per-address-space and shadow pages are shared across all address spaces. With SMM, a GFN can...

CVE-2026-98164

The Linux kernel contains a vulnerability in the KVM x86/mmu component. The function kvm_gfn_is_write_tracked() incorrectly checks only the supplied memslot, whereas page tracking is per-address-space and shadow pages are shared across all spaces. In an SMM context, a GFN can be write-tracked in ...

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Check write tracking in all address spaces kvmgfniswritetracked checks only the supplied memslot, but page tracking is per-address-space and shadow pages are shared across all address spaces. With SMM, a GFN can...

CVE-2026-64561

A flaw was found in KVM in the Linux kernel. This vulnerability occurs due to improper validation of memory management unit MMU page roots after these pages are made available. An attacker could exploit this by triggering a scenario where KVM attempts to map memory into an invalid root, causing...

UBUNTU-CVE-2026-64561

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Check for invalid/obsolete root after making MMU pages available Check for a "stale" page fault, i.e. for an invalid and/or obsolete root, after making MMU pages available for the shadow MMU. If reclaiming shadow pages...

CVE-2026-64561

CVE-2026-64561 is a Linux kernel vulnerability in KVM/x86 shadow MMU where, after reclaiming shadow MMU pages, an invalid/obsolete root could be created and then mapped. If a stale root is zapped and a child shadow page inherits that role, new child pages can be created as invalid, violating KVM’...

Linux Distros Unpatched Vulnerability : CVE-2026-64561

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - KVM: x86: Check for invalid/obsolete root after making MMU pages available Check for a stale page fault, i.e. for an invalid and/or obsolete root, after making...
