Split \"-Wl,\" flags that consume a following argument (such as \"-Wl,-rpath\", \"-Wl,--just-symbols\", and \"-Wl,-undefined\") previously accepted a bare second argument without a \"-Wl,\" prefix, which the compiler driver passes directly to the linker as a positional input file. Additionally, when using GNU ld.bfd, flags such as \"-framework\", \"-Wl,-framework\", \"-Wl,-undefined\", \"-Wl,--just-symbols\", \"-Wl,-R\", \"-Wl,-subsystem\", and (on non-Darwin platforms) \"-Wl,-sectcreate\" could cause ld.bfd to interpret their arguments as linker scripts if they named a regular file on disk. The go command now requires a \"-Wl,\" prefix on the second token of split \"-Wl,\" flags (except \"-Wl,-R\"), verifies that these flags do not reference linker script files, and disallows bare \"-Wl,--warn-backrefs-exclude\"."}],"affected":[{"vendor":"Go toolchain","product":"cmd/go","collectionURL":"https://pkg.go.dev","packageName":"cmd/go","versions":[{"version":"0","lessThan":"1.26.11","status":"affected","versionType":"semver"},{"version":"1.27.0-0","lessThan":"1.27.4","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-94: Improper Control of Generation of Code ('Code Injection')"}]}],"references":[{"url":"https://go.dev/cl/862150"},{"url":"https://go.dev/issue/82573"},{"url":"https://groups.google.com/g/golang-announce/c/iY8TY0wWgbM"},{"url":"https://pkg.go.dev/vuln/GO-2026-6854"}]}}}
