CVE-2022-42010Public exploit

Service crash via misnested type signature parsing

Published Oct 9, 2022 · Updated Jun 9, 2025

Denial of service in D-Bus before 1.12.24, 1.13.x, 1.14.x before 1.14.4, and 1.15.x before 1.15.2 allows local users to crash dbus-daemon. The signature validator in dbus-marshal-validate.c tracked parentheses and curly-brace nesting separately without ensuring each closer matched the latest opener. An authenticated local user who can send a crafted message to the system bus or a custom DBusServer can trigger an assertion failure in debug builds; upstream reported no concrete production-build crash example.
