CVE-2023-42755: Kernel: rsvp: out-of-bounds read in rsvp_classify()

First published: Wed Sep 20 2023(Updated: )

A flaw was found in rsvp_change(). The root cause is an slab-out-of-bound access, but since the offset to the original pointer is an `unsign int` fully controlled by users, the behavior is usually a wild pointer access.
