Vulnerability 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[].
