Cybersecurity researchers have disclosed details of a Linux local privilege escalation (LPE) flaw that could allow an unprivileged local user to obtain root.

The high-severity vulnerability tracked as CVE-2026-31431 (CVSS score: 7.8) has been codenamed Copy Fail by Xint.io and Theori.

“An unprivileged local user can write four controlled bytes into the page cache of any readable file on a Linux system, and use that to gain root,” the vulnerability research team at Xint.io and Theori said.

At its core, the vulnerability stems from a logic flaw in the Linux kernel’s cryptographic subsystem, specifically within the algif_aead module. The issue was introduced in a source code commit made in August 2017.

Successful exploitation of the shortcoming could allow a simple 732-byte Python script to edit a setuid binary and obtain root on essentially all Linux distributions shipped since 2017, including Amazon Linux, RHEL, SUSE, and Ubuntu. The Python exploit involves four steps -

• Open an AF_ALG socket and bind to authencesn(hmac(sha256),cbc(aes))
• Construct the shellcode payload
• Trigger the write operation to the kernel’s cached copy of “/usr/bin/su”
• Call execve(“/usr/bin/su”) to load the injected shellcode and run it as root

While the vulnerability is not remotely exploitable in isolation, a local unprivileged user can get root simply by corrupting the page cache of a setuid binary. The same primitive also has cross-container impacts as the page cache is shared across all processes on a system.

It’s amazing what a difference a little bit of time can make: Two years after kicking off what looked to be a long-shot campaign to push back on the practice of shutting down server-dependent videogames once they’re no longer profitable, Stop Killing Games founder Ross Scott and organizer Moritz Katzner appeared in front of the European Parliament to present their case—and it seemed to go very well.
