CVE-2016-4485
Published: 23 May 2016
The llc_cmsg_rcv function in net/llc/af_llc.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory by reading a message.
From the Ubuntu security team
Kangjie Lu discovered an information leak in the ANSI/IEEE 802.2 LLC type 2 Support implementations in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory.
