CVE-2025-38363
MediumSummary
W jądrze Linuxa zidentyfikowano podatność, która została naprawiona. W funkcji tegra_crtc_reset() alokowana jest nowa pamięć za pomocą kzalloc(), jednak nie przeprowadzono odpowiedniej weryfikacji stanu przed wywołaniem __drm_atomic_helper_crtc_reset.
Risk Assessment
Brak weryfikacji stanu przed alokacją pamięci może prowadzić do dereferencji wskaźnika null, co z kolei może skutkować awarią systemu lub nieprzewidywalnym zachowaniem.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, aby usunąć tę podatność oraz wprowadzenie dodatkowych kontroli stanu przed alokacją pamięci.
