Q: How severe is CVE-2011-1044?

CVE-2011-1044 has a CVSS v2 base score of 2.1, rated low. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

Q: What does CVE-2011-1044 affect?

Published advisories record a fix for linux kernel (NVD). Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.

NVD

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.
