CVE-2024-46759: hwmon: (adc128d818) Fix underflows seen when writing limit attributes

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.28% (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 019ef2d396363ecddc46e826153a842f8603799b, 05419d0056dcf7088687e561bb583cc06deba777, 2a3add62f183459a057336381ef3a896da01ce38; Azure Linux 3.0 ARM 6.6.51.1-5; Azure Linux 3.0 x64 6.6.51.1-5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 019ef2d396363ecddc46e826153a842f8603799b, 05419d0056dcf7088687e561bb583cc06deba777, 2a3add62f183459a057336381ef3a896da01ce38; Azure Linux 3.0 ARM 6.6.51.1-5; Azure Linux 3.0 x64 6.6.51.1-5 or later.
