CVE-2026-72016

CVE-2026-72016 relates to Linux kernel arm64 CPU hotplug handling. The issue arises when booting with maxcpus > present CPUs, where some CPUs are marked present but not registered, causing NULL kobject warnings in sysfs during cpuhp_smt_enable() as _cpu_up() triggers sysfs_create_group() with ...
