--- title: "CVE-2011-1079\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-2011-1079?format=md keywords: index, follow --- # CVE-2011-1079 Publication date 25 July 2011 Last updated 4 July 2026 --- Ubuntu priority **Low** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description The bnep\_sock\_ioctl function in net/bluetooth/bnep/sock.c in the Linux kernel before 2.6.39 does not ensure that a certain device field ends with a '\0' character, which allows local users to obtain potentially sensitive information from kernel stack memory, or cause a denial of service (BUG and system crash), via a BNEPCONNADD command. ### From the Ubuntu Security Team Vasiliy Kulikov discovered that the Bluetooth stack did not correctly check that device name strings were NULL terminated. A local attacker could exploit this to crash the system, leading to a denial of service, or leak contents of kernel stack memory, leading to a loss of privacy. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 11.10 oneiric | Not affected | | 11.04 natty | Fixed 2.6.38-9.43 | | 10.10 maverick | Fixed 2.6.35-30.52 | | 10.04 LTS lucid | Fixed 2.6.32-32.62 | | 8.04 LTS hardy | Fixed 2.6.24-29.93 | | linux-ec2 | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Ignored end of life | | 10.04 LTS lucid | Fixed 2.6.32-316.30 | | 8.04 LTS hardy | Not in release | | linux-fsl-imx51 | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.31-610.27 | | 8.04 LTS hardy | Not in release | | linux-lts-backport-maverick | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.35-30.54~lucid1 | | 8.04 LTS hardy | Not in release | | linux-lts-backport-natty | 11.10 oneiric | Not in release | | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.38-9.43~lucid1 | | 8.04 LTS hardy | Not in release | | linux-lts-backport-oneiric | 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 | 11.10 oneiric | Not in release | | 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 | | linux-ti-omap4 | 11.10 oneiric | Not affected | | 11.04 natty | Fixed 2.6.38-1209.13 | | 10.10 maverick | Fixed 2.6.35-903.23 | | 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-2011-1079?format=md#patch-details) ### Patch details For informational purposes only.
