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\".","epss":null,"exploits":[],"kev":null,"metrics":[],"modifiedAt":1794366795269,"publishedAt":1794366795269,"references":[{"source":"CNA: Go","tags":[],"url":"https://go.dev/cl/862154"},{"source":"CNA: Go","tags":[],"url":"https://go.dev/issue/82569"},{"source":"CNA: Go","tags":[],"url":"https://groups.google.com/g/golang-announce/c/iY8TY0wWgbM"},{"source":"CNA: Go","tags":[],"url":"https://pkg.go.dev/vuln/GO-2026-6850"}],"remediation":[],"revision":"4fe90310573769dd92dba4616a9a1dd2675a2fca1544618e10758e36f23db8f8","sources":[{"modifiedAt":1794366795269,"name":"CNA: Go","retrievedAt":1794370200262,"url":"https://www.cve.org/CVERecord?id=CVE-2026-97041"}],"ssvc":null,"status":"published","title":"Host linker flag injection via //go:cgo_* directives in cmd/compile and cmd/link","updatedAt":1794370200262}
