--- title: "CVE-2010-4158\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-2010-4158?format=md keywords: index, follow --- # CVE-2010-4158 Publication date 30 December 2010 Last updated 24 July 2024 --- Ubuntu priority **Low** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description The sk\_run\_filter function in net/core/filter.c in the Linux kernel before 2.6.36.2 does not check whether a certain memory location has been initialized before executing a (1) BPF\_S\_LD\_MEM or (2) BPF\_S\_LDX\_MEM instruction, which allows local users to obtain potentially sensitive information from kernel stack memory via a crafted socket filter. ### From the Ubuntu Security Team Dan Rosenberg discovered that the socket filters did not correctly initialize structure memory. A local attacker could create malicious filters to read portions of kernel stack memory, leading to a loss of privacy. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 11.04 natty | Fixed 2.6.37-5.13 | | 10.10 maverick | Fixed 2.6.35-25.43 | | 10.04 LTS lucid | Fixed 2.6.32-30.59 | | 9.10 karmic | Fixed 2.6.31-23.74 | | 8.04 LTS hardy | Fixed 2.6.24-29.87 | | 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 2.6.32-314.27 | | 9.10 karmic | Fixed 2.6.31-308.28 | | 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 2.6.31-610.27 | | 9.10 karmic | Ignored end of life | | 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 2.6.35-25.44~lucid1 | | 9.10 karmic | Not in release | | 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 2.6.32-416.33 | | 10.04 LTS lucid | Fixed 2.6.32-216.33 | | 9.10 karmic | Ignored end of life | | 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 | | 9.10 karmic | Not in release | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Fixed 2.6.15-57.94 | | linux-ti-omap4 | 11.04 natty | Not affected | | 10.10 maverick | Fixed 2.6.35-903.22 | | 10.04 LTS lucid | Not in release | | 9.10 karmic | 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-2010-4158?format=md#patch-details) ### Patch details For informational purposes only.
