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.

Security readout for executives and security teams

This is an old Linux ext3 filesystem kernel information leak. On Linux 2.4.x before 2.4.26, journal descriptor blocks could expose pieces of kernel memory onto the ext3 device. A privileged local user able to read the raw device could recover those fragments. Exposure is most likely on legacy Linux 2.4.x systems using ext3, especially unsupported appliances, embedded systems, or long-lived servers. The provided data does not identify modern affected distributions or non-Linux products. Treat this as a legacy-system cleanup issue, not an internet-scale emergency. Prioritize if Linux 2.4/ext3 systems still exist in sensitive environments, because kernel memory fragments may contain confidential data. Mitigation focus: Upgrade affected Linux 2.4.x kernels to 2.4.26 or vendor-fixed packages.; Follow applicable vendor advisories for Debian, Red Hat, Fedora, Trustix, and other listed distributions.; Restrict raw block device access to trusted administrators only..
