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. (NVD)
