Summary
W sterowniku Linux kernel dla akceleratora Ethos-U (accel/ethosu) wykryto podatność polegającą na błędzie w parserze strumienia komend. Funkcja NPU_SET_IFM_REGION używa maski 0x7f zamiast 0x7, co pozwala na indeksowanie poza zakresem tablicy region_size[] (rozmiar 8). Atakujący z przestrzeni użytkownika może przez odpowiednio spreparowane wywołanie zapisać dane poza przydzielonym buforem, powodując uszkodzenie sąsiednich danych sterty jądra.
Risk Assessment
Podatność umożliwia lokalnemu atakującemu z uprawnieniami użytkownika zapis poza granicami bufora w jądrze, co może prowadzić do eskalacji uprawnień, wycieku danych lub destabilizacji systemu.
