CVE-2025-40116
MediumSummary
W jądrze Linuxa naprawiono podatność związaną z dereferencją wskaźnika błędu w funkcji czyszczenia probe dla sterownika max3421-hcd. Funkcja kthread_run() może zwracać wskaźniki błędów, co wymaga sprawdzenia przed dereferencją wskaźnika max3421_hcd->spi_thread.
Risk Assessment
Brak odpowiedniego sprawdzenia wskaźników błędów może prowadzić do awarii systemu lub nieprzewidzianego zachowania, co stwarza ryzyko dla stabilności i bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, aby usunąć tę podatność oraz zapewnić odpowiednie sprawdzenie wskaźników błędów w kodzie.
