Updated libnl packages that fix a bug are now available for Red Hat Enterprise Linux 6.
The libnl package contains a convenience library to simplify using the Linux kernel netlink sockets interface for network manipulation.
Some nl_send_auto_complete() callers did not free the allocated message when errors were reported, resulting in libnl leaking memory. A problem in its own right, these small leaks also made it more work to detect memory leaks in other processes. With this update, allocated messages are freed correctly when nl_send_auto_complete() is called, and libnl no longer leaks memory in this circumstance.
All libnl users should upgrade to these updated packages, which fix this bug.
