CVE-2025-38531: iio: common: st_sensors: Fix use of uninitialize device structs

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: 0.16% (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 1f88548ec8ade8538eb970e36ffe5049b89d86f7, 3297a9016a45144883ec990bd4bd5b1d79cafb46, 610615c9668037e3eca11132063b93b2d945af13; cbl2 kernel 5.15.202.1-1 on CBL-Mariner 2.0 Release Notes.

Low priority for now. Upgrade to Linux Linux 1f88548ec8ade8538eb970e36ffe5049b89d86f7, 3297a9016a45144883ec990bd4bd5b1d79cafb46, 610615c9668037e3eca11132063b93b2d945af13; cbl2 kernel 5.15.202.1-1 on CBL-Mariner 2.0 Release Notes or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: iio: common: st_sensors: Fix use of uninitialize device structs Throughout the various probe functions &indio_dev->dev is used before it is initialized. This caused a kernel panic in st_sensors_power_enable() when the call to devm_regulator_bulk_get_enable() fails and then calls dev_err_probe() with the uninitialized device. This seems to only cause a panic with dev_err_probe(), dev_err(), dev_warn() and dev_info() don't seem to cause a panic, but are fixed as well. The issue is reported and traced here: [1]
