Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-401: Missing Release of Memory after Effective Lifetime, where the product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse. In Github.com/tinfoil factory/netfoil, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
