Summary
LoongArch: KVM: Handle the case that EIOINTC's coremap is empty
Details

In the Linux kernel, the following vulnerability has been resolved:

LoongArch: KVM: Handle the case that EIOINTC's coremap is empty

EIOINTC's coremap in eiointcupdatesw_coremap() can be empty, currently we get a cpuid with -1 in this case, but we actually need 0 because it's similar as the case that cpuid >= 4.

This fix an out-of-bounds access to kvmarch::phyidmap::phys_map[].
