CVE-2017-15031
HighCVSS 7.5Summary
Wszystkie wersje ARM Trusted Firmware do i włącznie z wersją 1.4 nie inicjalizują ani nie zapisują/przywracają rejestru PMCR_EL0, co może prowadzić do wycieku informacji o czasie w bezpiecznym świecie.
Risk Assessment
Możliwość wycieku informacji o czasie może umożliwić atakującym uzyskanie wrażliwych danych, co stanowi zagrożenie dla bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację do nowszej wersji ARM Trusted Firmware, która poprawia inicjalizację i zarządzanie rejestrem PMCR_EL0.
