The compiler and linker did not reject commas in \"//go:cgo_import_dynamic\", \"//go:cgo_export_dynamic\", \"//go:cgo_export_static\", \"//go:cgo_import_static\", and \"//go:cgo_dynamic_linker\" directives, and the linker passed the dynamic linker path using \"-Wl,--dynamic-linker,<path>\". Furthermore, the two-argument form of \"//go:cgo_import_dynamic\" (which is permitted in non-cgo Go source files) could overwrite the external symbol name of a symbol already marked for cgo export. A symbol name or dynamic linker path containing a comma or leading \"@\" could split \"-Wl,--export-dynamic-symbol=\" or \"-Wl,--dynamic-linker,\" into arbitrary host linker flags or response file arguments. The compiler and linker now reject commas in \"//go:cgo_*\" symbol and dynamic linker directives, the linker passes \"-Wl,--dynamic-linker=<path>\", and \"cgo_import_dynamic\" no longer overwrites symbols exported via \"cgo_export_dynamic\" or \"cgo_export_static\"."}],"affected":[{"source":"security@golang.org","affectedData":[{"vendor":"Go toolchain","product":"cmd/compile","defaultStatus":"unaffected","collectionURL":"https://pkg.go.dev","packageName":"cmd/compile","versions":[{"version":"0","lessThan":"1.26.11","versionType":"semver","status":"affected"},{"version":"1.27.0-0","lessThan":"1.27.4","versionType":"semver","status":"affected"}]},{"vendor":"Go toolchain","product":"cmd/link","defaultStatus":"unaffected","collectionURL":"https://pkg.go.dev","packageName":"cmd/link","versions":[{"version":"0","lessThan":"1.26.11","versionType":"semver","status":"affected"},{"version":"1.27.0-0","lessThan":"1.27.4","versionType":"semver","status":"affected"}]}]}],"metrics":{},"references":[{"url":"https://go.dev/cl/862154","source":"security@golang.org"},{"url":"https://go.dev/issue/82569","source":"security@golang.org"},{"url":"https://groups.google.com/g/golang-announce/c/iY8TY0wWgbM","source":"security@golang.org"},{"url":"https://pkg.go.dev/vuln/GO-2026-6850","source":"security@golang.org"}]}
