Overview

CVE-2008-3528 is a low-severity vulnerability affecting linux linux_kernel. It was published on September 27, 2008 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 error-reporting functionality in (1) fs/ext2/dir.c, (2) fs/ext3/dir.c, and possibly (3) fs/ext4/dir.c in the Linux kernel 2.6.26.5 does not limit the number of printk console messages that report directory corruption, which allows physically proximate attackers to cause a denial of service (temporary system hang) by mounting a filesystem that has corrupted dir->i_size and dir->i_blocks values and performing (a) read or (b) write operations. NOTE: there are limited scenarios in which this crosses privilege boundaries.

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.
