Dieses Problem erm\u00f6glicht es Angreifern, auf Informationen im Kernel-Speicher zuzugreifen und m\u00f6glicherweise ihre Privilegien im System zu erh\u00f6hen. <\/p>\n

Die zweite ein Problem<\/a><\/noindex> (CVE-2019-0154<\/a><\/noindex>) tritt auf Systemen mit Intel GPU der Gen8 und Gen9 (Broadwell und Skylake) auf und kann verwendet werden, um einen Denial-of-Service (Systemeinbruch) durch den Zugriff auf bestimmte GPU-Register \u00fcber MMIO zu initiieren, was den GPU in einen inkorrekten Zustand versetzt.<\/p>\n

Die Probleme wurden<\/a><\/noindex> in den Kernel-Updates 5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 behoben.
