MediumCVSS 5.5/10Last modified Jun 17, 2026

Description

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

HID: magicmouse: avoid memory leak in magicmouse_report_fixup()

The magicmouse_report_fixup() function was returning a newly kmemdup()-allocated buffer, but never freeing it.

The caller of report_fixup() does not take ownership of the returned pointer, but it *is* permitted to return a sub-portion of the input rdesc, whose lifetime is managed by the caller.
