"value": "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 > /sys/devices/system/cpu/cpu1/online\n echo 1 > /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->mems_allowed) which is not guaranteed to have\nnodes to the rebind routine. Use cs->effective_mems instead, which is\nguaranteed to have a non-empty nodemask once we reach that code path.\n\n[ david: add a comment, slightly rephrase description ]"
