Exploitation and risk

Source status

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Host linker flag injection via //go:cgo_* directives in cmd/compile and cmd/link

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".

Additional publisher context

EUVD source date text has no stated timezone and is retained without inventing a UTC instant. Related bulletin membership is not an alias, common cause or applicability claim. A missing vector with a zero score is treated as unrated. Complete vendor/product and underlying source evidence remains in the original JSON.
