AI-suggested

A patch is available and has been released by Ubuntu as part of updated Linux kernel packages. Users should update their systems to the fixed kernel versions and reboot to apply the changes. Due to an ABI change, recompilation and reinstallation of third-party kernel modules may be required. Follow vendor instructions for updating and rebuilding kernel modules as needed.

Description

A vulnerability in the Linux kernel's iio subsystem for the st_lsm6dsx sensor driver was fixed. The issue involved improper handling of sensors without event detection capability, leading to a NULL pointer dereference when userspace attempted to configure accelerometer wakeup events on unsupported sensors. This could cause kernel crashes or instability. The vulnerability affects specific Linux kernel versions prior to 6.8.0-1057.60~22.04.1 and related versions. A patch is available and included in updated Linux kernel packages distributed by Ubuntu. Users should update and reboot to apply the fix.
