If it was for personal use, surely there would be some kind of consumer organization or ombudsman one could contact for advice?

For B2B, I guess the local chamber of commerce might be able to advice.

Does anyone know how to mitigate this one? Is it sufficient to disable the esp4/esp6/rxrpc modules?

New comment by cpach in "CVE-2026-31431: Copy Fail vs. rootless containers"

cpach — Wed, 06 May 2026 20:36:28 +0000

No, I haven’t.

My concern is to try to understand the mechanisms of the exploit.

Copy Fail is not simply ”hey, kernel, give me root”. I would say it’s more general than that. It’s rather: ”Hey, kernel, when you present file /foo to a process, make the contents of that file appear according to my wishes”. Which can be used (in various ways) to advance the attacker’s position.

That’s why I think it’s interesting to ponder if that power allows the attacker to simply sneak past security policies such as allowPrivilegeEscalation=false.
