CVE-2017-5549

New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

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.
