CVE-2025-39690:
Linux Debian vulnerability analysis and mitigation
Overview
CVE-2025-39690 affects the Linux kernel's Industrial I/O (IIO) accelerometer driver for the SCA3300 sensor. The vulnerability was discovered and disclosed on September 5, 2025, and involves a potential leak of uninitialized stack data to userspace through the channels array in the driver (NVD).
Technical details
The vulnerability exists in the iio:accel:sca3300 driver where uninitialized stack data could potentially be exposed to userspace due to the channels array not being properly zeroed before use. This security issue was identified in the Linux kernel's Industrial I/O subsystem (NVD).
Impact
The vulnerability could lead to information disclosure, potentially exposing sensitive kernel memory data to unprivileged users through the affected accelerometer driver (NVD).
Mitigation and workarounds
The vulnerability has been resolved by ensuring that the channels array is properly zeroed before use. A fix has been implemented in the Linux kernel codebase (NVD).
