CVE-2024-53113

Local system crash via cpuset migration race

Published Dec 2, 2024 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel allows local users to crash the system during bulk page allocation under cpusets. A task migrating between cpusets can change current->mems_allowed while first_zones_zonelist() traverses NUMA nodes, leaving ac.preferred_zoneref without a zone before alloc_pages_bulk_noprof() dereferences it. Triggering the race requires local low-privileged execution, enabled cpusets, task migration between cpusets, and a NUMA configuration; the bounded consequence is a kernel crash.
