CVE-2026-64226

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> sched_ext: Avoid UAF in scx_root_enable_workfn() init failure path<br /> <br /> In scx_root_enable_workfn(), put_task_struct(p) is called before scx_error()<br /> dereferences p-&gt;comm and p-&gt;pid. If the iterator&amp;#39;s reference is the last<br /> drop, the task is freed synchronously and the deref becomes a UAF.<br /> <br /> Move put_task_struct() past scx_error().
