GHSA-3g4q-2f67-2gvh: netfoil has a resource leak in LRU cache
Summary
When an entry was removed from the LRU cache, a pointer to the removed element was not properly cleaned up.
Impact
A local attacker can get netfoil to use more memory. By default this is limited to 100MB via systemd, which would trigger service restarts when reached.
