In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: soc-acpi-intel-rpl-match: add missing empty item
There is no linksnum in struct sndsocacpimach {}, and we test !link->numadr as a condition to end the loop in hdasdwmachineselect(). So an empty item in struct sndsocacpilinkadr array is required.
