CVE-2026-80718

A flaw was found in the Linux kernel. Specifically, within the mm/percpu-km module, the pcpucreatechunk function incorrectly calculates the size of a bitmap used for tracking memory pages. This miscalculation can lead to a bitmap overflow, where data is written beyond the intended memory boundary...
