{"id":"DEBIAN-CVE-2022-49034","details":"In the Linux kernel, the following vulnerability has been resolved:  sh: cpuinfo: Fix a warning for CONFIG_CPUMASK_OFFSTACK  When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected, cpu_max_bits_warn() generates a runtime warning similar as below when showing /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit) instead of NR_CPUS to iterate CPUs.
