Summary
In the Linux kernel, the following vulnerability has been resolved:
net: do not pass flow_id to set_rps_cpu()
Blamed commit made the assumption that the RPS table for each receive
queue would have the same size, and that it would not change.
Compute flow_id in set_rps_cpu(), do not assume we can use the value
computed by get_rps_cpu(). Otherwise we risk out-of-bound access
and/or crashes.
