CVE-2026-23139
MediumSummary
W jądrze Linuxa zidentyfikowano podatność w module netfilter, która dotyczy aktualizacji zmiennej last_gc. Zmienna ta jest aktualizowana za każdym razem, gdy śledzona jest nowa konekcja, nawet jeśli nie przeprowadzono zbierania śmieci (GC).
Risk Assessment
Nieprawidłowe aktualizowanie last_gc może prowadzić do nieefektywnego zarządzania zasobami, co w konsekwencji może wpłynąć na wydajność systemu oraz bezpieczeństwo połączeń sieciowych.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, w której ta podatność została naprawiona, aby zapewnić prawidłowe działanie mechanizmu zarządzania połączeniami.
