In the Linux kernel before 4.13.5, a local user could create keyrings for other users via keyctl commands, setting unwanted defaults or causing a denial of service.

Affected: Ubuntu:14.04:LTS: linux

Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel did not properly validate meta block groups. An attacker with physical access could use this to specially craft an ext4 image that causes a denial of service (system crash). (CVE-2016-10208)

It was discovered that an information disclosure vulnerability existed in the ACPI implementation of the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory addresses). (CVE-2017-11472)

It was discovered that a buffer overflow existed in the ACPI table parsing implementation in the Linux kernel. A local attacker could use this to construct a malicious ACPI table that, when loaded, caused a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-11473)

It was discovered that the generic SCSI driver in the Linux kernel did not properly initialize data returned to user space in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-14991)

It was discovered that a race condition existed in the packet fanout implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15649)

Andrey Konovalov discovered that the Ultra Wide Band driver in the Linux kernel did not properly check for an error condition. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly ex…
