CVE-2025-38531
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: iio: common: st_sensors: Fix use of uninitialize device structs Throughout the various probe functions &indio_dev->dev is used before it is initialized. This caused a kernel panic in st_sensors_power_enable() when the call to devm_regulator_bulk_get_enable() fails and then calls dev_err_probe() with the uninitialized device. This seems to only cause a panic with dev_err_probe(), dev_err(), dev_warn() and dev_info() don't seem to cause a panic, but are fixed as well. The issue is reported and traced here: [1]

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iio: common: st_sensors: Se corrige el uso de estructuras de dispositivo sin inicializar. En las diversas funciones de sondeo, se usa &indio_dev->dev antes de su inicialización. Esto provocaba un pánico del kernel en st_sensors_power_enable() cuando la llamada a devm_regulator_bulk_get_enable() falla y luego se llama a dev_err_probe() con el dispositivo sin inicializar. Esto parece causar un pánico solo con dev_err_probe(); dev_err(), dev_warn() y dev_info() no parecen causarlo, pero también se han corregido. El problema se reporta y rastrea aquí: [1]"
