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