HIGHNVD 7.87.8—

7.8

In the Linux kernel, the following vulnerability has been resolved:

LoongArch: Make cpumask_of_node() robust against NUMA_NO_NODE

The arch definition of cpumask_of_node() cannot handle NUMA_NO_NODE - which is a valid index - so add a check for this.

CVSS v3: 7.8
EG Score: 7.8(high)
