Overview

CVE-2011-1044 is a low-severity vulnerability affecting linux linux_kernel. It was published on February 18, 2011 and has a CVSS 2.0 base score of 2.1 (LOW).

This vulnerability has a CVSS 2.0 base score of 2.1, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

The ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel before 2.6.37 does not initialize a certain response buffer, which allows local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially filled, a different vulnerability than CVE-2010-4649.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
