CVE-2026-72010

CVE-2026-72010 — Linux kernel (cgroup/cpuset) memo policy rebinding : A divisive divide-by-zero could occur when rebinding a VMA mempolicy with MPOL_F_RELATIVE_NODES during CPU hotplug if cpuset.mems was never set. The issue arises because the rebind path used cs->mems_allowed (which may have ...

CVE-2026-72010 cgroup/cpuset: rebind mm mempolicy to effective_mems, not mems_allowed

In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: rebind mm mempolicy to effectivemems, not memsallowed Creating a child cpuset where cpuset.mems is never set leads to a div/0 when a VMA mempolicy with MPOLFRELATIVENODES rebinds in response to a CPU hotplug event...

CVE-2026-64373

A flaw was found in the Linux kernel's CPU frequency scaling cpufreq subsystem. During a system reboot, a race condition can occur when the system attempts to suspend CPU frequency operations while CPU hotplug operations are still active. This can lead to a null pointer dereference, which may cau...
