Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: rebind mm mempolicy to
 effective_mems, not mems_allowed Creating a child cpuset where cpuset.mems is never set leads to a div/0
 when a VMA mempolicy with MPOL_F_RELATIVE_NODES rebinds in response to a CPU hotplug event. Reproduction
 steps: 1) Create a cgroup w/ cpuset controls (do not set cpuset.mems) 2) Move the task into the child
 cpuset 3) Create a VMA mempolicy for that task with MPOL_F_RELATIVE_NODES 4) unplug and hotplug a cpu echo
 0 > /sys/devices/system/cpu/cpu1/online echo 1 > /sys/devices/system/cpu/cpu1/online 5) mempolicy rebind
 does a div/0 in mpol_relative_nodemask on the call to __nodes_fold() The cpuset code passes
 (cs->mems_allowed) which is not guaranteed to have nodes to the rebind routine. Use cs->effective_mems
 instead, which is guaranteed to have a non-empty nodemask once we reach that code path. [ david: add a
 comment, slightly rephrase description ] (CVE-2026-72010)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.21 or later.
