CVE-2024-50198

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: light: veml6030: fix IIO device retrieval from embedded device<br /> <br /> The dev pointer that is received as an argument in the<br /> in_illuminance_period_available_show function references the device<br /> embedded in the IIO device, not in the i2c client.<br /> <br /> dev_to_iio_dev() must be used to accessthe right data. The current<br /> implementation leads to a segmentation fault on every attempt to read<br /> the attribute because indio_dev gets a NULL assignment.<br /> <br /> This bug has been present since the first appearance of the driver,<br /> apparently since the last version (V6) before getting applied. A<br /> constant attribute was used until then, and the last modifications might<br /> have not been tested again.
