{"id":"CVE-2026-97041","published":"2026-11-11T05:19:58.417","lastModified":"2026-11-11T05:19:58.417","description":"Building a malicious package containing \"//go:cgo_*\" compiler directives could inject arbitrary flags into the external linker invocation on ELF platforms. 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\".","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://go.dev/cl/862154","tags":[]},{"url":"https://go.dev/issue/82569","tags":[]},{"url":"https://groups.google.com/g/golang-announce/c/iY8TY0wWgbM","tags":[]},{"url":"https://pkg.go.dev/vuln/GO-2026-6850","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
