CVE-2026-72010

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A division by zero occurs in the cgroup/cpuset component when a child cpuset is created without setting cpuset.mems. This happens during a VMA mempolicy rebind in response to a CPU hotplug event when using MPOL F RELATIVE NODES. The issue stems from the cpuset code passing cs->mems allowed to the rebind routine, which may not contain nodes, instead of using cs->effective mems. The failure occurs within the mpol relative nodemask function during a call to nodes fold().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
