--- title: "CVE-2011-2213\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2011-2213?format=md keywords: index, follow --- # CVE-2011-2213 Publication date 29 August 2011 Last updated 4 July 2026 --- Ubuntu priority **Low** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description The inet\_diag\_bc\_audit function in net/ipv4/inet\_diag.c in the Linux kernel before 2.6.39.3 does not properly audit INET\_DIAG bytecode, which allows local users to cause a denial of service (kernel infinite loop) via crafted INET\_DIAG\_REQ\_BYTECODE instructions in a netlink message, as demonstrated by an INET\_DIAG\_BC\_JMP instruction with a zero yes value, a different vulnerability than CVE-2010-3880. ### From the Ubuntu Security Team Dan Rosenberg discovered that the IPv4 diagnostic routines did not correctly validate certain requests. A local attacker could exploit this to consume CPU resources, leading to a denial of service. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux-goldfish | 14.04 LTS trusty | Not in release | | 13.10 saucy | Ignored | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 10.04 LTS lucid | Not in release | | linux-grouper | 14.04 LTS trusty | Not in release | | 13.10 saucy | Ignored | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 10.04 LTS lucid | Not in release | | linux-maguro | 14.04 LTS trusty | Not in release | | 13.10 saucy | Ignored | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 10.04 LTS lucid | Not in release | | linux-mako | 14.04 LTS trusty | Not in release | | 13.10 saucy | Ignored | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 10.04 LTS lucid | Not in release | | linux-manta | 14.04 LTS trusty | Not in release | | 13.10 saucy | Ignored | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 10.04 LTS lucid | Not in release | | linux-flo | 14.04 LTS trusty | Not in release | | 13.10 saucy | Not in release | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 10.04 LTS lucid | Not in release | | linux | 14.04 LTS trusty | Not affected | | 13.10 saucy | Not affected | | 12.10 quantal | Not affected | | 12.04 LTS precise | Not affected | | 11.10 oneiric | Not affected | | 11.04 natty | Fixed 2.6.38-12.51 | | 10.10 maverick | Fixed 2.6.35-30.60 | | 10.04 LTS lucid | Fixed 2.6.32-34.77 | | 8.04 LTS hardy | Fixed 2.6.24-29.94 | | linux-ec2 | 14.04 LTS trusty | Not in release | | 13.10 saucy | Not in release | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Ignored end of life | | 10.04 LTS lucid | Fixed 2.6.32-318.38 | | 8.04 LTS hardy | Not in release | | linux-fsl-imx51 | 14.04 LTS trusty | Not in release | | 13.10 saucy | Not in release | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.31-611.29 | | 8.04 LTS hardy | Not in release | | linux-lts-backport-maverick | 14.04 LTS trusty | Not in release | | 13.10 saucy | Not in release | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.35-30.60~lucid1 | | 8.04 LTS hardy | Not in release | | linux-lts-backport-natty | 14.04 LTS trusty | Not in release | | 13.10 saucy | Not in release | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.38-12.51~lucid1 | | 8.04 LTS hardy | Not in release | | linux-lts-backport-oneiric | 14.04 LTS trusty | Not in release | | 13.10 saucy | Not in release | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Not affected | | 8.04 LTS hardy | Not in release | | linux-mvl-dove | 14.04 LTS trusty | Not in release | | 13.10 saucy | Not in release | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not in release | | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Fixed 2.6.32-418.35 | | 10.04 LTS lucid | Fixed 2.6.32-218.35 | | 8.04 LTS hardy | Not in release | | linux-ti-omap4 | 14.04 LTS trusty | Not in release | | 13.10 saucy | Not affected | | 12.10 quantal | Not affected | | 12.04 LTS precise | Not affected | | 11.10 oneiric | Not affected | | 11.04 natty | Fixed 2.6.38-1209.16 | | 10.10 maverick | Fixed 2.6.35-903.25 | | 10.04 LTS lucid | Not in release | | 8.04 LTS hardy | Not in release | --- * [How can I get the fixes?](https://ubuntu.com/security/cves/about#security) * [What do statuses mean?](https://ubuntu.com/security/cves/about#statuses) * [Patch details](https://ubuntu.com/security/CVE-2011-2213?format=md#patch-details) ### Patch details For informational purposes only.
