Description

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 eiointc_update_sw_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 kvm_arch::phyid_map::phys_map[].

Affected configurations

• linux linux kernel (>= 6.13.1 < 6.18.21) • linux linux kernel (>= 6.19 < 6.19.11) • linux linux kernel 6.13 • linux linux kernel 7.0
