CVE-2016-5243MEDIUM
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 tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel through 4.6.3 does not properly copy a certain string, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message.
