CVE-2026-98666: iio: gyro: adis16136: fix unprotected debugfs reads

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 2b498df75d6c29aa3e760127ae0f0003df598b53, 3558b125b034003b04e89d0d7b38733a08d3fc49, b05e768420352d9051f86c1a1f20f44fa046ba45; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes.

Low priority for now. Upgrade to Linux Linux 2b498df75d6c29aa3e760127ae0f0003df598b53, 3558b125b034003b04e89d0d7b38733a08d3fc49, b05e768420352d9051f86c1a1f20f44fa046ba45; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: iio: gyro: adis16136: fix unprotected debugfs reads The serial_number file operations are open coded and never call debugfs_file_get(), which debugfs_create_file_unsafe() requires. debugfs_remove_recursive() therefore does not wait for a read in progress, and unbind frees the iio_dev underneath it. Use debugfs_create_file() instead.
