Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

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.


Remediation

Install update from vendor's website.
