CVE-2025-37969
Linux Debian vulnerability analysis and mitigation

Overview

CVE-2025-37969 is a vulnerability discovered in the Linux kernel affecting the stlsm6dsx driver component. The vulnerability was published on May 20, 2025, and involves a potential infinite loop condition in the stlsm6dsxreadtagged_fifo function (NVD).

Technical details

The vulnerability occurs when the patternlen parameter is equal to zero while the device FIFO is not empty, which can cause the stlsm6dsxreadtagged_fifo function to enter an infinite loop. This condition affects the Industrial I/O (IIO) subsystem's IMU driver for the ST LSM6DSX sensor (NVD).

Impact

The vulnerability can result in a system lockup when the specific conditions are met, potentially affecting system availability and performance of devices using the ST LSM6DSX sensor driver (NVD).

Mitigation and workarounds

The vulnerability has been resolved in the Linux kernel through a patch that prevents the stlsm6dsxreadtaggedfifo function from entering an infinite loop when the pattern_len is zero and the device FIFO is not empty (NVD).
