CVE-2025-39675
MediumSummary
W jądrze Linuxa zidentyfikowano podatność polegającą na braku sprawdzenia wartości zwracanej przez funkcję get_first_active_display() w funkcji mod_hdcp_hdcp1_create_session(). Wartość zwracana może być nullem, co prowadzi do potencjalnych problemów.
Risk Assessment
Brak odpowiedniego sprawdzenia wartości zwracanej 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, w której ta podatność została naprawiona, aby zapewnić odpowiednie sprawdzenie wartości zwracanej przez funkcję.
