CVE-2020-1459
HighSummary
Istnieje podatność na ujawnienie informacji w implementacjach ARM, które wykorzystują spekulacyjne wykonanie w przepływie sterowania poprzez analizę kanału bocznego, znaną jako 'spekulacja w linii prostej'. Aby wykorzystać tę podatność, atakujący z lokalnymi uprawnieniami musiałby uruchomić specjalnie przygotowaną aplikację.
Risk Assessment
Podatność ta może prowadzić do ujawnienia wrażliwych informacji w systemach wykorzystujących spekulacyjne wykonanie, co stanowi zagrożenie dla poufności danych organizacji.
Recommendation
Zaleca się zastosowanie aktualizacji zabezpieczeń, która omija spekulacyjne wykonanie, aby zminimalizować ryzyko związane z tą podatnością.

Original NVD description (English source)
An information disclosure vulnerability exists on ARM implementations that use speculative execution in control flow via a side-channel analysis, aka "straight-line speculation." To exploit this vulnerability, an attacker with local privileges would need to run a specially crafted application. The security update addresses the vulnerability by bypassing the speculative execution.
