An attacker could use this to construct a malicious ext4 image\nthat, when mounted, could cause a denial of service (system crash).\n(CVE-2018-10880)\n\nIt was discovered that the alarmtimer implementation in the Linux kernel\ncontained an integer overflow vulnerability. A local attacker could use\nthis to cause a denial of service. (CVE-2018-13053)\n\nWen Xu discovered that the f2fs filesystem implementation in the Linux\nkernel did not properly validate metadata. An attacker could use this to\nconstruct a malicious f2fs image that, when mounted, could cause a denial\nof service (system crash). (CVE-2018-13096)\n\nWen Xu and Po-Ning Tseng discovered that the btrfs filesystem\nimplementation in the Linux kernel did not properly handle relocations in\nsome situations. An attacker could use this to construct a malicious btrfs\nimage that, when mounted, could cause a denial of service (system crash).\n(CVE-2018-14609)\n\nWen Xu discovered that the HFS+ filesystem implementation in the Linux\nkernel did not properly handle malformed catalog data in some situations.\nAn attacker could use this to construct a malicious HFS+ image that, when\nmounted, could cause a denial of service (system crash). (CVE-2018-14617)\n\nJann Horn discovered that the procfs file system implementation in the\nLinux kernel did not properly restrict the ability to inspect the kernel\nstack of an arbitrary task. A local attacker could use this to expose\nsensitive information. (CVE-2018-17972)\n\nIt was discovered that the KVM implementation in the Linux kernel on ARM\n64bit processors did not properly handle some ioctls. An attacker with the\nprivilege to create KVM-based virtual machines could use this to cause a\ndenial of service (host system crash) or execute arbitrary code in the\nhost.
