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.
A flaw was found in the Linux kernel's Human Interface Device (HID) sensor custom driver. When creating sysfs groups for custom sensor fields, the hid_sensor_custom_add_attributes() function fails to properly clean up previously created groups if an error occurs. This improper resource management could lead to system instability or a denial of service (DoS) condition.
