CVE-2026-72286

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM with Secure Encrypted Virtualization SEV and Secure Nested Paging SNP virtual machines. The intra-host migration and mirroring feature is not fully implemented for SEV-SNP VMs. This incomplete implementation means that critic...

CVE-2026-72284

A flaw was found in the Kernel-based Virtual Machine KVM subsystem of the Linux kernel, specifically in the handling of Paravirtualized End Of Interrupt PV EOI for x86 virtual CPUs. A local attacker in a guest virtual machine could exploit a race condition where a virtual CPU disables PV EOIs aft...

CVE-2026-72283

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem. This vulnerability occurs when the system fails to update an Interrupt Remapping Table Entry IRTE for a bypass operation, which can leave a pointer to a memory location that has already been freed a 'dangling...

CVE-2026-72282

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. The kvmiobusgetdev function, responsible for retrieving I/O bus devices, could return a device that is only matched by its memory address. This creates a race condition where the device might be deallocated before...

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-2026-72294

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component, specifically within the LoongArch architecture. The kvmvcpuioctlinterrupt function, which can be invoked from userspace, lacks proper validation of interrupt requests. This missing validity check could allow a loca...

CVE-2026-72293

A flaw was found in the kernel's KVM Kernel-based Virtual Machine s390 vsie component. A missing radixtreepreload call in the gaccessshadowfault function can prevent the system from guaranteeing forward progress. This could lead to system instability or a Denial of Service DoS, where the system...

CVE-2026-72281

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for arm64 architectures. This vulnerability involves an issue with memory accounting for protected guest faults. During the teardown process, the system may incorrectly manage long-term memory pins, potentially leading to...

CVE-2026-72285

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine TDX Trust Domain Extensions module. A local attacker, by concurrently modifying the CPUID entry count during the initialization of a virtual machine, could cause the CPUID parsing to access memory beyond the intended...

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 ...

CVE-2026-72290

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for s390 PCI. During the setup of guest interrupt forwarding, a reference count refcount to the Guest Interrupt Service Call GISC may not be properly released if subsequent setup steps fail. This resource leak can lead to...
