GO-2025-3428

Arbitrary code execution during build on darwin in cmd/go

Quick fix

GO-2025-3428 — toolchain: upgrade to the fixed version with the command below.

go get toolchain@v1.24.0-rc.3

Details

On Darwin, building a Go module which contains CGO can trigger arbitrary code execution when using the Apple version of ld, due to usage of the @executable_path, @loader_path, or @rpath special values in a "#cgo LDFLAGS" directive. This issue only affected go1.24rc2.
