CVE-2026-89626

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.
