--- title: "CVE-2012-0028\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-2012-0028?format=md keywords: index, follow --- # CVE-2012-0028 Publication date 4 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 robust futex implementation in the Linux kernel before 2.6.28 does not properly handle processes that make exec system calls, which allows local users to cause a denial of service or possibly gain privileges by writing to a memory location in a child process. ### From the Ubuntu Security Team A flaw was found in how the linux kernel handles user-space held futexs. An unprivileged user could exploit this flaw to cause a denial of service or possibly elevate privileges. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 13.04 raring | Not affected | | 12.10 quantal | Not affected | | 12.04 LTS precise | Not affected | | 11.10 oneiric | Not affected | | 11.04 natty | Not affected | | 10.10 maverick | Ignored end of life, was pending | | 10.04 LTS lucid | Not affected | | 8.04 LTS hardy | Fixed 2.6.24-31.99 | | linux-armadaxp | 13.04 raring | Not in release | | 12.10 quantal | Not affected | | 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 | 13.04 raring | 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 | Not affected | | 8.04 LTS hardy | Not in release | | linux-fsl-imx51 | 13.04 raring | 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-lts-backport-maverick | 13.04 raring | 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 | Ignored end of life | | 8.04 LTS hardy | Not in release | | linux-lts-backport-natty | 13.04 raring | 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-lts-backport-oneiric | 13.04 raring | 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-lts-quantal | 13.04 raring | Not in release | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not affected | | 11.10 oneiric | Not in release | | 10.04 LTS lucid | Not in release | | 8.04 LTS hardy | Not in release | | linux-lts-raring | 13.04 raring | Not in release | | 12.10 quantal | Not in release | | 12.04 LTS precise | Not affected | | 11.10 oneiric | Not in release | | 10.04 LTS lucid | Not in release | | 8.04 LTS hardy | Not in release | | linux-mvl-dove | 13.04 raring | 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, was pending | | 10.04 LTS lucid | Ignored end of life | | 8.04 LTS hardy | Not in release | | linux-ti-omap4 | 13.04 raring | Not affected | | 12.10 quantal | Not affected | | 12.04 LTS precise | Not affected | | 11.10 oneiric | Not affected | | 11.04 natty | Not affected | | 10.10 maverick | Ignored end of life, was pending | | 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-2012-0028?format=md#patch-details) ### Patch details For informational purposes only.
