Name of the Vulnerable Software and Affected Versions Linux kernel version 2.6

Description The issue is related to the Journaling Block Device (JBD) functionality in the Linux kernel, specifically the cleanup journal tail function. It allows local users to cause a denial of service, resulting in an assertion error and kernel oops, by using an ext3 or ext4 image with an invalid log first block value.

Recommendations For Linux kernel version 2.6, consider restricting access to the JBD functionality until a patch is available. As a temporary workaround, avoid using the cleanup journal tail function with ext3 or ext4 images that may contain invalid log first block values.
