The klsi_105_get_line_state function in drivers/usb/serial/kl5kusb105.c in the Linux kernel before 4.9.5 places uninitialized heap-memory contents into a log entry upon a failure to read the line status, which allows local users to obtain sensitive information by reading the log.

CVE-2016-10208 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
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

Ubuntu 16.10.
Ben Harris discovered that the Linux kernel would strip extended privilege
attributes of files when performing a failed unprivileged system call. A
