Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: fix eswitch code memory leak in reset scenario
Add simple eswitch mode checker in attaching VF procedure and allocate
required port representor memory structures only in switchdev mode.
The reset flows triggers VF (if present) detach/attach procedure.
It might involve VF port representor(s) re-creation if the device is
configured is switchdev mode (not legacy one).
The memory was blindly allocated in current implementation,
regardless of the mode and not freed if in legacy mode.
