CVE-2016-4580
Published: 23 May 2016
The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.
From the Ubuntu security team
Kangjie Lu discovered an information leak in the X.25 Call Request handling in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory.
