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

sh: cpuinfo: Fix a warning for CONFIGCPUMASKOFFSTACK

When CONFIGCPUMASKOFFSTACK and CONFIGDEBUGPERCPUMAPS are selected, cpumaxbitswarn() generates a runtime warning similar as below when showing /proc/cpuinfo. Fix this by using nrcpuids (the runtime limit) instead of NRCPUS to iterate CPUs.
