An attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2018-15471)\n\nIt was discovered that the generic SCSI driver in the Linux kernel did not\nproperly enforce permissions on kernel memory access. A local attacker\ncould use this to expose sensitive information or possibly elevate\nprivileges. (CVE-2017-13168)\n\nIt was discovered that an integer overflow existed in the CD-ROM driver of\nthe Linux kernel. A local attacker could use this to expose sensitive\ninformation (kernel memory). (CVE-2018-16658)\n\nIt was discovered that an integer overflow existed in the HID Bluetooth\nimplementation in the Linux kernel that could lead to a buffer overwrite.\nAn attacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code.
