Overview

CVE-2022-50223 is a medium-severity vulnerability. It was published on June 18, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

Technical description

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

LoongArch: cpuinfo: Fix a warning for CONFIG_CPUMASK_OFFSTACK

When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS is selected,

cpu_max_bits_warn() generates a runtime warning similar as below while

we show /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit)

instead of NR_CPUS to iterate CPUs.
