What to do
AI-suggested
A fix has been applied in the Linux kernel to correct the base address calculation in kvm_eiointc_regs_access(). Users should update to the fixed kernel version once available. Patch status is not explicitly confirmed in the input; therefore, check the official Linux kernel advisories for the exact fixed version and apply the update accordingly.
Description
A vulnerability in the Linux kernel's KVM implementation for LoongArch architecture was fixed by correcting the base address calculation in the function kvm_eiointc_regs_access(). The issue involved improper calculation of the register base address due to incorrect type conversion of the array base address before adding an offset.
