Description
Уязвимость компонента mm/gup.c ядра операционной системы Linux существует из-за недостаточной проверки состояния ресурса при возможности его совместного использования. Эксплуатация уязвимости может позволить нарушителю, действующему локально, повысить свои привилегии путем некорректного использования функции копирования при записи (COW) для записи данных в области памяти, предназначенных только для чтения
