Copy Fail exposes Linux to root by exploiting kernel crypto path

Security researchers disclosed Copy Fail (CVE-2026-31431), a Linux local privilege-escalation flaw in the algif_aead kernel module that lets an unprivileged user corrupt a page cache and elevate to root across major distributions since 2017. The issue is portable, cross-container, and can be triggered with a small Python script, prompting advisories from major distros. Exploitation is local (not remote) but remains highly dangerous due to its ease and wide impact.

"CherryLoader Malware: Mimicking CherryTree for Privilege Escalation"

A new Go-based malware loader called CherryLoader has been discovered, masquerading as the legitimate CherryTree note-taking application, to deliver privilege escalation tools such as PrintSpoofer and JuicyPotatoNG onto compromised hosts for follow-on exploitation. It packs modularized features that allow threat actors to swap exploits without recompiling code and uses encryption methods and anti-analysis techniques to evade detection. The loader is distributed through a RAR archive file and leverages fileless techniques for execution, ultimately setting up persistence on the host and disarming Microsoft Defender.
