HID: asus: avoid memory leak in asus_report_fixup() (CVE-2026-31524)

Summary

HID: asus: avoid memory leak in asus_report_fixup()

Original description

The description as published by the source.

In the Linux kernel, the following vulnerability has been resolved:

HID: asus: avoid memory leak in asus_report_fixup()

The asus_report_fixup() function was returning a newly allocated
kmemdup()-allocated buffer, but never freeing it. Switch to
devm_kzalloc() to ensure the memory is managed and freed automatically
when the device is removed.

The caller of report_fixup() does not take ownership of the returned
pointer, but it is permitted to return a pointer whose lifetime is at
least that of the input buffer.

Also fix a harmless out-of-bounds read by copying only the original
descriptor size.
