Detailed vulnerability description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The ext3 code in Linux 2.4.x before 2.4.26 does not properly initialize journal descriptor blocks, which causes an information leak in which in-memory data is written to the device for the ext3 file system, which allows privileged users to obtain portions of kernel memory by reading the raw device.
