--- title: "CVE-2011-2022\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-2011-2022?format=md keywords: index, follow --- # CVE-2011-2022 Publication date 9 May 2011 Last updated 24 July 2024 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description The agp\_generic\_remove\_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 does not validate a certain start parameter, which allows local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC\_UNBIND agp\_ioctl ioctl call, a different vulnerability than CVE-2011-1745. ### From the Ubuntu Security Team Vasiliy Kulikov discovered that the AGP driver did not check certain ioctl values. A local attacker with access to the video subsystem could exploit this to crash the system, leading to a denial of service, or possibly gain root privileges. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 11.04 natty | Fixed 2.6.38-10.44 | | 10.10 maverick | Fixed 2.6.35-30.52 | | 10.04 LTS lucid | Fixed 2.6.32-33.64 | | 8.04 LTS hardy | Fixed 2.6.24-29.91 | | 6.06 LTS dapper | Not in release | | linux-ec2 | 11.04 natty | Not in release | | 10.10 maverick | Ignored end of life | | 10.04 LTS lucid | Fixed 2.6.32-317.32 | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-fsl-imx51 | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.31-609.26 | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-lts-backport-maverick | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.35-30.54~lucid1 | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-lts-backport-natty | 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 | 11.04 natty | Not in release | | 10.10 maverick | Fixed 2.6.32-417.34 | | 10.04 LTS lucid | Fixed 2.6.32-217.34 | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-source-2.6.15 | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Not in release | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Ignored | | linux-ti-omap4 | 11.04 natty | Fixed 2.6.38-1209.15 | | 10.10 maverick | Fixed 2.6.35-903.23 | | 10.04 LTS lucid | Not in release | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | 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-2011-2022?format=md#patch-details) ### Patch details For informational purposes only.
