CVE-2026-89626
Summary
by MITRE • 09/11/2026
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.
