In the Linux kernel, the following vulnerability has been resolved:
HID: sensor: custom: Fix field sysfs group cleanup on failure
hid_sensor_custom_add_attributes() creates one sysfs group for each
custom sensor field. If sysfs_create_group() fails after some groups
have already been created, the function returns the error without
removing the previously created groups. Add a local unwind path to remove the groups that were already created.
With enable_sensor exposed only after the field attributes are ready,
this path can free sensor_inst->fields without leaving enable_sensor
able to access pointers into that array.
