SUSE CVE-2026-46316
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Drop the translation cache reference only for the erased entry vgicitsinvalidatecache walks the per-ITS translation cache with xaforeach and drops the cache's reference on each entry with vgicputirq. It puts...
CVE-2026-46316
A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for ARM64, specifically within the vgic-its component. This vulnerability occurs when multiple concurrent operations incorrectly drop the translation cache's reference to an entry more than once during cache invalidation. Thi...

CVE-2026-46317
The CVE pertains to the Linux kernel KVM on arm64. kvm->arch.nested_mmus[] could be walked under mmu_lock, while kvm_vcpu_init_nested() reallocates and frees the old buffer, risking dereferencing a freed array via the MMU notifier path. The fix moves allocation of the new array outside the loc...

Linux Distros Unpatched Vulnerability : CVE-2026-46317
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - KVM: arm64: Reassign nestedmmus array behind mmulock kvm-arch.nestedmmus is walked under kvm-mmulock, including from the MMU notifier path kvmunmapgfnrange -...
CVE-2026-46147
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Fix pin leak and publication ordering in pkvminitvcpu Two bugs exist in the vCPU initialisation path: 1. If a check fails after hyppinsharedmem succeeds, the cleanup path jumps to 'unlock' without calling unpinhostvcp...
Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Avoid consuming a stale esr value when an SError occurs When any exception other than an IRQ occurs, the CPU updates the ESREL2 register with the exception syndrome. An SError may also become pending, and will be...

CVE-2026-43351
The CVE-2026-43351 issue affects the Linux kernel’s KVM on arm64 when creating a virtual GIC. If vgic_allocate_private_irqs_locked() fails, kvm_vgic_create() can exit before vgic dist regions are initialised, and kvm_vgic_dist_destroy() may then attempt to free uninitialised data, risking a crash...

CVE-2026-23425
CVE-2026-23425 (Linux kernel KVM arm64) — The issue stems from non-protected pKVM guests where the hypervisor copies only the KVM_ARCH_FLAG_ID_REGS_INITIALIZED flag from the host to the hypervisor during pkvm_init_features_from_host, while the actual id_regs data are not initialized. This can cau...
