CopyFail Go

Most Linux LPEs need a race window or a kernel-specific offset.Copy Fail is a straight-line logic flaw — it needs neither.The same 732-byte Python script static Go binary roots every Linux distribution shipped since 2017.

A Go implementation of CVE-2026-31431. In case you need a static binary and no Python dependency.

See copy.fail for more info.
