Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Fix transport_* TOCTOU
Transport assignment may race with module unload. Protect new_transport from becoming a stale pointer.
This also takes care of an insecure call in vsock_use_local_transport(); add a lockdep assert.
