    It was discovered that Avahi incorrectly terminated when processing browser records with wide-area
    disabled. An attacker could possibly use this issue to cause Avahi to crash, resulting in a denial of
    service. (CVE-2025-68276)

    It was discovered that Avahi incorrectly terminated when processing unsolicited CNAME records pointing to
    resource records with short TTLs. An attacker could possibly use this issue to cause Avahi to crash,
    resulting in a denial of service. (CVE-2025-68468)

    It was discovered that Avahi incorrectly terminated when processing unsolicited CNAME records in quick
    succession. An attacker could possibly use this issue to cause Avahi to crash, resulting in a denial of
    service. (CVE-2025-68471)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
