Linux Kernel Vulnerability in cpuinfo Component from Vendor
CVE-2022-50210
What is CVE-2022-50210?
A vulnerability exists within the Linux kernel's cpuinfo component that triggers runtime warnings during the execution of the /proc/cpuinfo interface. This issue arises when both CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are configured, leading to a warning due to incorrect CPU iteration using NR_CPUS instead of the runtime limit nr_cpu_ids. This error may complicate system diagnostics and affect overall performance monitoring.
