Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.6% (FIRST EPSS); higher than 85.6% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: kernel-image-2.4.16-lart (Debian:3.0) 20040419; kernel-image-2.4.16-netwinder (Debian:3.0) 20040419; kernel-image-2.4.16-riscpc (Debian:3.0) 20040419.

Low priority for now. Upgrade to kernel-image-2.4.16-lart (Debian:3.0) 20040419; kernel-image-2.4.16-netwinder (Debian:3.0) 20040419; kernel-image-2.4.16-riscpc (Debian:3.0) 20040419 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
