  "details": "In the Linux kernel, the following vulnerability has been resolved:  net: psp: check for device unregister when creating assoc  psp_assoc_device_get_locked() obtains a psp_dev reference via psp_dev_get_for_sock() (which uses psp_dev_tryget() under RCU); it then acquires psd-\u003elock and drops the reference. Before the lock is taken, psp_dev_unregister() can run to completion: take psd-\u003elock, clear out state, unlock, drop the registration reference.  The expectation is that the lock prevents device unregistration, but much like with netdevs special care has to be taken when \"upgrading\" a reference to a locked device. Add the missing check if device is still alive. psp_dev_is_registered() exists already but had no callers, which makes me wonder if I either forgot to add this or lost the check during refactoring...",
