CVE-2026-80665

This vulnerability affects the Linux kernel's KVM arm64 nested virtualization subsystem. The root cause is in kvm_handle_vncr_abort() , which incorrectly assumes that a -EFAULT return from kvm_translate_vncr() always conveys an abort. In practice, "late" failures on S1 translation output (e.g., a...

CVE-2026-64562

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM nested virtualization nVMX feature. This vulnerability occurs because the shadow Virtual Machine Control Structure VMCS is freed prematurely while still being referenced. Due to asynchronous operations, a virtual CPU vCPU mig...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: removed the spurious WARN message when writing to ZCREL2. It is entirely possible for a guest to write to the ZCREL2 sysreg alias while in a nested context. This is expected if FEATNV2 is advertised to the L1...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Update x2APIC MSR intercepts if AVIC is inhibited while L2 is active Always update x2APIC MSR intercepts for L1 when AVIC is deactivated, even if L2 is active and KVM uses a separate MSR bitmap to run L2. If AVIC is ful...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: KVM: nVMX: Moving the consistency check between vTPR and TPR Threshold to “normal” checks Moving the off-by-default consistency check for vmcs12.tprthreshold versus the virtual APIC vTPR to the “normal” control checks is...

CVE-2026-74516

A flaw was found in KVM Kernel-based Virtual Machine. When the Advanced Virtual Interrupt Controller AVIC is inhibited while a nested guest L2 is active, KVM fails to properly update x2APIC MSR intercepts for the primary guest L1. This allows the L1 guest to read the host's APIC state, send...

SUSE CVE-2026-72278

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Re-translate VNCR before injecting abort KVM faults in the VNCR page with FOLLWRITE whenever the guest aborts for a write, similar to how a regular stage-2 mapping is handled. It is entirely possible that the gues...

CVE-2026-72279

A flaw was found in the KVM Kernel-based Virtual Machine component of the Linux kernel. KVM on arm64 architectures incorrectly maps the L1 Virtual Nested Control Register VNCR into the host stage-1, failing to respect read-only memory regions. This could allow a malicious guest to write to a...

CVE-2026-72280

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine for ARM64 architectures. A guest operating system, when operating in a nested virtualization environment, could trigger a hypervisor panic hyppanic by writing to the ZCREL2 system register alias. This issue leads to a denial ...
