In the Linux kernel, the following vulnerability has been resolved:
net: phonet: free phonet device after RCU grace period
phonet device destroy() removes a phonet device from the per-net device
list with list del rcu(), but frees it immediately. RCU readers walking
the same list can still hold a pointer to the object after it has been
removed, leading to a slab-use-after-free.
Use kfree rcu(), matching the lifetime rule already used by
phonet address del() for the same object type.
