CVE-2026-98164
The Linux kernel contains a vulnerability in the KVM x86/mmu component related to write tracking. Specifically, the kvm_gfn_is_write_tracked() function only checks the supplied memslot, whereas page tracking is per-address-space and shadow pages are shared. This allows a GFN to be write-tracked i...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the KVM x86 MMU where the kvm gfn is write tracked function only checks the supplied memslot. Because page tracking is per-address-space and shadow pages are shared...
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...
kernel: KVM: x86: Check for invalid/obsolete root *after* making MMU pages available
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...
