CVE-2026-23403
MediumSummary
W jądrze Linuxa zidentyfikowano podatność związaną z wyciekiem pamięci w funkcji verify_header, która ustawia `*ns = NULL` przy każdym wywołaniu. Powoduje to wyciek ciągu nazw przestrzeni, który został przydzielony w poprzednich iteracjach podczas rozpakowywania wielu profili.
Risk Assessment
Wyciek pamięci może prowadzić do zwiększonego zużycia zasobów systemowych, co w dłuższej perspektywie może wpłynąć na stabilność i wydajność systemu. Może to również narazić system na inne potencjalne ataki związane z zarządzaniem pamięcią.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemu pod kątem nieprawidłowego zużycia pamięci.
