CVE-2026-78422

A flaw was found in zbuspolkit. The Subject::newforowner function incorrectly encodes the user ID UID as an unsigned 32-bit integer instead of a signed 32-bit integer when communicating with the PolicyKit polkit authorization framework. This type mismatch causes polkit to disregard the provided U...
