USN-3822-1

Summary: linux vulnerabilities

Details: Jim Mattson discovered that the KVM implementation in the Linux kernel mismanages the #BP and #OF exceptions. A local attacker in a guest virtual machine could use this to cause a denial of service (guest OS crash). (CVE-2016-9588) It was discovered that the generic SCSI driver in the Linux kernel did not properly enforce permissions on kernel memory access. A local attacker could use this to expose sensitive information or possibly elevate privileges. (CVE-2017-13168) Andrey Konovalov discovered that the CDC USB Ethernet driver did not properly validate device descriptors. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16649) It was discovered that an integer overflow existed in the CD-ROM driver of the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-16658) It was discovered that an integer overflow existed in the HID Bluetooth implementation in the Linux kernel that could lead to a buffer overwrite. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-9363)
