CVE-2025-37970: iio: imu: st_lsm6dsx: fix possible lockup in st_lsm6dsx_read_fifo

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: 0.18% (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 159ca7f18129834b6f4c7eae67de48e96c752fc9, 3bb6c02d6fe8347ce1785016d135ff539c20043c, 6c4a5000618a8c44200d455c92e2f2a4db264717; azl3 kernel 6.6.85.1-4 on Azure Linux 3.0 6.6.92.2-1; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.92.2-1.

Low priority for now. Upgrade to Linux Linux 159ca7f18129834b6f4c7eae67de48e96c752fc9, 3bb6c02d6fe8347ce1785016d135ff539c20043c, 6c4a5000618a8c44200d455c92e2f2a4db264717; azl3 kernel 6.6.85.1-4 on Azure Linux 3.0 6.6.92.2-1; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.92.2-1 or later.
