--- title: "CVE-2011-0716\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-2011-0716?format=md keywords: index, follow --- # CVE-2011-0716 Publication date 12 January 2012 Last updated 4 July 2026 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description The br\_multicast\_add\_group function in net/bridge/br\_multicast.c in the Linux kernel before 2.6.38, when a certain Ethernet bridge configuration is used, allows local users to cause a denial of service (memory corruption and system crash) by sending IGMP packets to a local interface. ### From the Ubuntu Security Team A flaw was found in the Linux Ethernet bridge's handling of IGMP (Internet Group Management Protocol) packets. An unprivileged local user could exploit this flaw to crash the system. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 12.04 LTS precise | Not affected | | 11.10 oneiric | Not affected | | 11.04 natty | Not affected | | 10.10 maverick | Fixed 2.6.35-32.66 | | 10.04 LTS lucid | Not affected | | 8.04 LTS hardy | Not affected | | linux-armadaxp | 12.04 LTS precise | Not affected | | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.04 LTS lucid | Not in release | | 8.04 LTS hardy | Not in release | | linux-ec2 | 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 | Not affected | | 8.04 LTS hardy | Not in release | | linux-fsl-imx51 | 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-lts-backport-maverick | 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 2.6.35-32.66~lucid1 | | 8.04 LTS hardy | Not in release | | linux-lts-backport-natty | 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-lts-backport-oneiric | 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 | 12.04 LTS precise | Not in release | | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Not affected | | 10.04 LTS lucid | Ignored end of life | | 8.04 LTS hardy | Not in release | | linux-ti-omap4 | 12.04 LTS precise | Not affected | | 11.10 oneiric | Not affected | | 11.04 natty | Not affected | | 10.10 maverick | Fixed 2.6.35-903.31 | | 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-2011-0716?format=md#patch-details) ### Patch details For informational purposes only.
