CVE-2004-0447: Unknown vulnerability in Linux before 2.4.26 for IA64 allows local users to cause a denial of service, with unknown impact.

HighCVSS 7.2 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.44% (FIRST EPSS).
  • No special conditions are required; it is repeatable.
  • Fixed version: kernel-image-sparc-2.4 (Debian:3.0) 26woody1; kernel-patch-2.4.19-mips (Debian:3.0) 2.4.19-0.020911.1.woody5; kernel-source-2.4.16 (Debian:3.0) 2.4.16-1woody2.

Low priority for now. Upgrade to kernel-image-sparc-2.4 (Debian:3.0) 26woody1; kernel-patch-2.4.19-mips (Debian:3.0) 2.4.19-0.020911.1.woody5; kernel-source-2.4.16 (Debian:3.0) 2.4.16-1woody2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Unknown vulnerability in Linux before 2.4.26 for IA64 allows local users to cause a denial of service, with unknown impact. NOTE: due to a typo, this issue was accidentally assigned CVE-2004-0477. This is the proper candidate to use for the Linux local DoS.
