CVE-2025-38109
MediumSummary
W jądrze Linuksa naprawiono podatność związaną z nieprawidłowym usuwaniem wirtualnych portów (vports) podczas procesu zamykania, co prowadziło do błędu użycia po zwolnieniu (UAF). Problem dotyczył tabeli ACL dla ruchu przychodzącego, która nie była poprawnie niszczona na urządzeniach BlueField.
Risk Assessment
Podatność ta może prowadzić do nieautoryzowanego dostępu do zasobów sieciowych, co stwarza ryzyko dla integralności i poufności danych w organizacji.
Recommendation
Zaleca się aktualizację jądra Linuksa do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemów w celu wykrycia potencjalnych nieautoryzowanych działań.
