CVE-2025-38034
MediumSummary
W jądrze Linuxa zidentyfikowano podatność związaną z nieprawidłową kolejnością argumentów w funkcji btrfs__prelim_ref. Błąd ten prowadzi do dereferencji wskaźnika NULL, ponieważ zmienna oldref jest przekazywana jako NULL.
Risk Assessment
Podatność ta może prowadzić do awarii systemu lub nieprzewidzianego zachowania aplikacji korzystających z systemu plików Btrfs, co może wpłynąć na stabilność i dostępność usług.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, w której ta podatność została naprawiona, aby zminimalizować ryzyko wystąpienia problemów związanych z dereferencją wskaźnika NULL.
