原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
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.
