CVE-2025-38072
MediumSummary
W jądrze systemu Linux naprawiono podatność związaną z błędem dzielenia w funkcji nd_label_data_init() w module libnvdimm/labels. Problem występuje, gdy wadliwe urządzenie pamięci CXL zwraca nieprawidłowy rozmiar LSA w informacji o urządzeniu pamięci.
Risk Assessment
W przypadku wykorzystania tej podatności, może dojść do awarii systemu lub nieprzewidzianego zachowania aplikacji korzystających z pamięci CXL, co może prowadzić do utraty danych.
Recommendation
Zaleca się aktualizację jądra systemu Linux do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie urządzeń pamięci CXL w celu wykrycia ewentualnych problemów.
