CVE-2011-2189  (opens in a new tab)
CWE-400  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:6 kernel-firmware.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-firmware package and not the kernel-firmware package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

net/core/net_namespace.c in the Linux kernel 2.6.32 and earlier does not properly handle a high rate of creation and cleanup of network namespaces, which makes it easier for remote attackers to cause a denial of service (memory consumption) via requests to a daemon that requires a separate namespace per connection, as demonstrated by vsftpd.
