Medium: kernel

Issue Overview:

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.

Affected Packages:

kernel

Issue Correction:
Run yum update kernel to update your system. You will need to reboot your system in order for the new kernel to be running.
