CVE-2026-64561

CVE-2026-64561 is a Linux kernel KVM/x86 vulnerability related to the shadow MMU; after MMU pages are made available, reclaiming a zapped in-use root can lead to mapping memory into an invalid root, violating the invariant that invalid pages are not on the active MMU page list. The flaw has histo...

CVE-2026-64562

CVE-2026-64562 affects the Linux kernel KVM nVMX feature. The issue arises when freeing the shadow VMCS: free_nested() frees the shadow VMCS while vmcs01 still points to it, which is asynchronous with respect to loaded_vmcs_clear(). As a result, a vCPU may migrate before the pointer is cleared, a...
