    CVE-2026-44074

    Netatalk 2.1.0 through 4.4.2 combines multiple errno values using bitwise OR, resulting in incorrect error codes when multiple error conditions occur simultaneously, which may allow a remote attacker to cause a minor service disruption via conditions that trigger incorrect error-handling paths.
