CVE-2024-38805: iSCSI Remote Memory Corruption and Denial of Service

MediumCVSS 6.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 0.23% (FIRST EPSS).
  • Someone on the same network segment can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: edk2 (Debian:13) 2025.02-8+deb13u1; edk2 (Debian:14) 2025.02-9; ovmf (openSUSE:Tumbleweed) 202505-2.1.

Low priority for now. Upgrade to edk2 (Debian:13) 2025.02-8+deb13u1; edk2 (Debian:14) 2025.02-9; ovmf (openSUSE:Tumbleweed) 202505-2.1 or later.
