CVE-2025-71198

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: imu: st_lsm6dsx: fix iio_chan_spec for sensors without event detection<br /> <br /> The st_lsm6dsx_acc_channels array of struct iio_chan_spec has a non-NULL<br /> event_spec field, indicating support for IIO events. However, event<br /> detection is not supported for all sensors, and if userspace tries to<br /> configure accelerometer wakeup events on a sensor device that does not<br /> support them (e.g. LSM6DS0), st_lsm6dsx_write_event() dereferences a NULL<br /> pointer when trying to write to the wakeup register.<br /> Define an additional struct iio_chan_spec array whose members have a NULL<br /> event_spec field, and use this array instead of st_lsm6dsx_acc_channels for<br /> sensors without event detection capability.
