A parkedthread doesn't need that wakeup to leave. A spurious wakeup or apreemption after the store is enough for the task to go away.\nSo if the coredump client is preempted between the store andwake_up_process() the thread can exit and be freed in the meantime andtry_to_wake_up() takes pi_lock in freed memory.\nHold rcu across the loop.\nhttps://www.cve.org/CVERecord?id=CVE-2026-99218https://git.kernel.org/stable/c/fd0fbe84312fda2fc187428c92c50b7d03a9d24chttps://git.kernel.org/stable/c/71146c437bae59e5280f657965dc6d006ee3989bhttps://git.kernel.org/stable/c/0fce73efee40c65ce26641c5d93942462f9e8307https://git.kernel.org/stable/c/16e94ed90b1b02398e044d41fd1db34828daa08ehttps://git.kernel.org/stable/c/a0f09ff4c6b93312e565cfe75d76c3a551a3ec4chttps://git.kernel.org/stable/c/b0eca0edddf4c1dbaf6d1f6a8636b4235f5bc573#kernel
