  "description": "In the Linux kernel, the following vulnerability has been resolved:  LoongArch: KVM: Make kvm_get_vcpu_by_cpuid() more robust  kvm_get_vcpu_by_cpuid() takes a cpuid parameter whose type is int, so cpuid can be negative. Let kvm_get_vcpu_by_cpuid() return NULL for this case so as to make it more robust.  This fix an out-of-bounds access to kvm_arch::phyid_map::phys_map[].",
