It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-72010 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-72010/ (Markdown: https://insights.sbomify.com/CVE-2026-72010/index.md)","id":"CVE-2026-72010","markdown":"https://insights.sbomify.com/CVE-2026-72010/index.md","name":"CVE-2026-72010","record":{"aliases":["BELL-CVE-2026-72010","DEBIAN-CVE-2026-72010","GHSA-m46q-74wj-vxmp","UBUNTU-CVE-2026-72010"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can cause a kernel crash via division by zero in cpuset memory policy rebinding during CPU hotplug events.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncgroup/cpuset: rebind mm mempolicy to effective_mems, not mems_allowed\n\nCreating a child cpuset where cpuset.mems is never set leads to a div/0\nwhen a VMA mempolicy with MPOL_F_RELATIVE_NODES rebinds in response to a\nCPU hotplug event.\n\nReproduction steps:\n 1) Create a cgroup w/ cpuset controls (do not set cpuset.mems)\n 2) Move the task into the child cpuset\n 3) Create a VMA mempolicy for that task with MPOL_F_RELATIVE_NODES\n 4) unplug and hotplug a cpu\n      echo 0 \u003e /sys/devices/system/cpu/cpu1/online\n      echo 1 \u003e /sys/devices/system/cpu/cpu1/online\n 5) mempolicy rebind does a div/0 in mpol_relative_nodemask on the\n    call to __nodes_fold()\n\nThe cpuset code passes (cs-\u003emems_allowed) which is not guaranteed to have\nnodes to the rebind routine.
