CVE-2024-50024: net: Fix an unsafe loop on the list

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.27% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 1cdec792b2450105b1314c5123a9a0452cb2c2f0, 1dae9f1187189bc09ff6d25ca97ead711f7e26f9, 3be342e0332a7c83eb26fbb22bf156fdca467a5d; azl3 kernel 6.6.56.1-5 on Azure Linux 3.0 6.6.57.1-1; azl3 kernel 6.6.57.1-1 on Azure Linux 3.0 6.6.57.1-1.

Low priority for now. Upgrade to Linux Linux 1cdec792b2450105b1314c5123a9a0452cb2c2f0, 1dae9f1187189bc09ff6d25ca97ead711f7e26f9, 3be342e0332a7c83eb26fbb22bf156fdca467a5d; azl3 kernel 6.6.56.1-5 on Azure Linux 3.0 6.6.57.1-1; azl3 kernel 6.6.57.1-1 on Azure Linux 3.0 6.6.57.1-1 or later.
