Overview

CVE-2009-3288 is a medium-severity vulnerability affecting kernel linux_kernel. It was published on September 22, 2009 and has a CVSS 2.0 base score of 4.9 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 4.9, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

The sg_build_indirect function in drivers/scsi/sg.c in Linux kernel 2.6.28-rc1 through 2.6.31-rc8 uses an incorrect variable when accessing an array, which allows local users to cause a denial of service (kernel OOPS and NULL pointer dereference), as demonstrated by using xcdroast to duplicate a CD. NOTE: this is only exploitable by users who can open the cdrom device.

Remediation

Check the references section for vendor advisories and patches from kernel. 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.
