CVE-2026-46147
CVE-2026-46147 concerns the Linux kernel KVM on ARM64, where two bugs in vCPU initialisation can leak pin references to host vCPU/SVE pages and allow observation of a partially initialised vCPU object. The fixes extract a helper for vCPU registration, ensure proper unpinning on error, and enforce...

CVE-2026-31593
CVE-2026-31593 is a Linux kernel KVM SEV SNP issue. The vulnerability arises when updating an already-launched and encrypted vCPU state: attempting to sync the vCPU's VMSA can trigger an SEV-SNP cryptographic memory protection (RMP) violation, causing a host panic/DoS. Technical details across mu...

CVE-2026-31558
The CVE-2026-31558 issue affects the Linux kernel LoongArch KVM component. The vulnerable code is kvm_get_vcpu_by_cpuid(), which accepts a cpuid as int; if cpuid is negative, the function could access kvm_arch::phyid_map::phys_map[] out of bounds. The documented fix makes kvm_get_vcpu_by_cpuid() ...
The vulnerability of the kvm_xen_init_vcpu() function in the arch/x86/kvm/xen.c module of the virtualization subsystem on the x86 kernel of the Linux operating system allows a hacker to cause a service failure.
The vulnerability of the kvmxeninitvcpu function in the arch/x86/kvm/xen.c module of the virtualization subsystem on the x86-based Linux kernel platform is related to improper initialization. Exploiting this vulnerability can allow an attacker to cause a service failure...
