CVE-2026-31764

A flaw was found in the Linux kernel's st_lsm6dsx Industrial I/O (IIO) Inertial Measurement Unit (IMU) driver. A local user can trigger an out-of-bounds access by writing to the buffer sampling frequency sysfs attribute. This occurs when the st_lsm6dsx_check_odr() function attempts to access an array with an index derived from an unsupported sensor ID, leading to memory corruption. The most significant impact of this flaw is a denial of service (DoS), which could lead to system instability.
