Description OSIDB Bzimport 2026-05-06 13:07:16 UTC 
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.
