CVE-2026-31431 - Copy Fail - Linux kernel crypto vulnerability

[randallb]

There is a a temporary fix of disabling the algif_aead kernel module posted on CERT and other sites. This affects most Linux distributions and was proven on RHEL 10.1 kernel release 45. Status from CERT as of 4/29 was that the RHEL fix is unknown status. All other versions of Linux are either not fixed or also in an unknown status. This only is a local privilege escalation and is not dire if you do not allow access to the systems from remote sites.
