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
