CVE-2026-31564

In the Linux kernel, the following vulnerability has been resolved: LoongArch: KVM: Fix base address calculation in kvm_eiointc_regs_access() In function kvm_eiointc_regs_access(), the register base address is caculated from array base address plus offset, the offset is absolute value from the base address. The data type of array base address is u64, it should be converted into the "void *" type and then plus the offset.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: LoongArch: KVM: Corrección del cálculo de la dirección base en kvm_eiointc_regs_access() En la función kvm_eiointc_regs_access(), la dirección base del registro se calcula a partir de la dirección base del array más el desplazamiento; el desplazamiento es un valor absoluto desde la dirección base. El tipo de dato de la dirección base del array es u64, debería ser convertido al tipo ’void *’ y luego sumarle el desplazamiento.
