CVE-2017-5549
Published: 6 February 2017
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.
From the Ubuntu Security Team
It was discovered that the KLSI KL5KUSB105 serial-to-USB device driver in the Linux kernel did not properly initialize memory related to logging. A local attacker could use this to expose sensitive information (kernel memory).
