CVE-2026-80873

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine component on ARM64 systems. When a nested guest hypervisor L2 encounters a System Error SError exception, the ESREL2 register, which provides details about the exception, is not properly updated. This can cause the guest L2...

CVE-2026-98467

The Linux kernel contains a vulnerability in the KVM subsystem for arm64 architectures. A race condition occurs during the teardown of a nested guest, where the kvm->arch.mmu.pgt can be set to NULL concurrently with kvm_nested_s2_unmap() and kvm_nested_s2_wp() operations. Specifically, stage2_...

kernel: KVM: SVM: Update x2APIC MSR intercepts if AVIC is inhibited while L2 is active

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...

CVE-2026-89513

CVE-2026-89513 is an integer overflow in the Linux kernel's KVM (RISC-V) component. The SBI PMU EVENT_GET_INFO handler stores num_events * sizeof(*einfo) in a 32-bit integer; on RV64, a guest-supplied num_events = 0x10000001 truncates the allocation to 16 bytes while KVM still loops over the orig...
