NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-tools-debuginfo package and not the kernel-tools-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

The rds_recvmsg function in net/rds/recv.c in the Linux kernel before 3.0.44 does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a (1) recvfrom or (2) recvmsg system call on an RDS socket.
