The vulnerability of the kvm_eiointc regs_access() function in the arch/loongarch/kvm/intc/eiointc.c module, which is part of the LoongArch architecture support for the Linux operating system, allows a attacker to cause a service failure.

The vulnerability of the kvmeiointc regsaccess function in the arch/loongarch/kvm/intc/eiointc.c module of the LoongArch architecture support for the Linux operating system is related to incorrect conversion of numerical value types. Exploiting this vulnerability could allow an attacker to cause ...

In the Linux kernel, the following vulnerability has been resolved: LoongArch: KVM: Check the validity of “numcpu” from user space. The maximum supported CPU number is EIOINTCROUTEMAXVCPUS. For the irchip EIOINTC, validation of the CPU number is added to prevent array pointer overflow...

SUSE CVE-2026-31569

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 eiointcupdateswcoremap 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...

CVE-2026-31569

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. When a specific internal data structure, known as EIOINTC's coremap, is empty, the system incorrectly processes a processor ID. This error can lead to an out-of-bounds memory access, meaning the system tries to rea...
