In the Linux kernel, the following vulnerability has been resolved:
RDMA/cxgb4: Cancel reg work before freeing device on remove
c4iw uld state change() queues reg work to register the RDMA device.
c4iw remove() can free ctx->dev while this work is pending or running,
leaving c4iw register device() accessing the freed device.
Cancel reg work before removing the device. The registration work can
tear down ctx->dev when registration fails, so do not unregister or
deallocate it again in that case.
