CVE-2016-5244

Published: 27 June 2016

The rds_inc_info_copy function in net/rds/recv.c in the Linux kernel through 4.6.3 does not initialize a certain structure member, which allows remote attackers to obtain sensitive information from kernel stack memory by reading an RDS message.

From the Ubuntu security team

Kangjie Lu discovered an information leak in the Reliable Datagram Sockets (RDS) implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory.

Priority
