       I spent the last couple of days examining the source code and understanding the Copy.Fail vulnerability in detail. This vulnerability happens on the shoulders of 4 key components:- Page cache- AF_ALG- algif_aead- splice()In this video, I talk about these components and demonstrate how the CVE-2026-31431 vulnerability allows attackers to gain root access by modifying the “su” entry in the page cache.https://youtu.be/OftLQ1uPh4M#copyfail #linux #video
