    Ariel Silver discovered that CUPS incorrectly handled username comparisons during authorization checks. A
    local attacker could possibly use this issue to gain unauthorized access to restricted operations.
    (CVE-2026-27447)

    Asim Viladi Oglu Manizada discovered that CUPS incorrectly handled notify-recipient-uri values in the RSS
    notifier. A remote attacker could possibly use this issue to overwrite lp-writable files and cause a
    denial of service. (CVE-2026-34978)

    Jacob Newman discovered that CUPS incorrectly handled filter option strings when processing job
    attributes. An attacker could use this issue to cause CUPS to crash, resulting in a denial of service, or
    possibly execute arbitrary code. (CVE-2026-34979)

    Asim Viladi Oglu Manizada discovered that CUPS incorrectly handled page-border values in shared PostScript
    queues. A remote attacker could possibly use this issue to execute arbitrary code. (CVE-2026-34980)

    Asim Viladi Oglu Manizada discovered that CUPS incorrectly handled localhost authentication to attacker-
    controlled IPP services. A local attacker could possibly use this issue to overwrite arbitrary files and
    execute arbitrary code. (CVE-2026-34990)

    Tomer Fichman discovered that CUPS incorrectly handled negative job-password-supported values. A local
    attacker could possibly use this issue to cause CUPS to crash, resulting in a denial of service.
    (CVE-2026-39314)

    Tomer Fichman discovered that CUPS incorrectly handled temporary printer deletion. An attacker could
    possibly use this issue to cause CUPS to crash, resulting in a denial of service, or to execute arbitrary
    code. (CVE-2026-39316)

    Tomer Fichman discovered that CUPS incorrectly handled certain malformed SNMP responses. An attacker could
    possibly use this issue to obtain sensitive information. (CVE-2026-41079)
