CVE-2026-43212
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
