Vulnerability from github – Published: 2026-04-22 15:31 – Updated: 2026-04-28 18:30In the Linux kernel, the following vulnerability has been resolved:
HID: apple: avoid memory leak in apple_report_fixup()
The apple_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.
