CVE-2024-50019 kthread: unpark only parked kthread

In the Linux kernel, the following vulnerability has been resolved: kthread: unpark only parked kthread Calling into kthread unparking unconditionally is mostly harmless when the kthread is already unparked. The wake up is then simply ignored because the target is not in TASKPARKED state. However...

CVE-2024-50019

In CVE-2024-50019 the IBM bulletin documents a Linux kernel issue where kthread unparked-per-CPU threads could be woken up during stop. Root cause: calling kthread_unpark unconditionally before ensuring the thread is inactive can cause a wakeup on a per-CPU kthread that has been bound via kthread...
