A remote attacker could possibly use this issue to perform NSEC3 impersonation attacks, bypassing DNSSEC validation. (CVE-2026-10723)</p> <p>It was discovered that Bind incorrectly handled Key Records using the PRIVATEDNS algorithm. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service. (CVE-2026-10822)</p> <p>It was discovered that Bind incorrectly handled wildcard CNAME expansion in Response Policy Zones. A remote attacker could possibly use this issue to bypass configured RPZ policies. (CVE-2026-11331)</p> <p>It was discovered that Bind performed unnecessary validation of DNSSEC signed records. A remote attacker could possibly use this issue to cause Bind to use excessive resources, leading to a denial of service. This issue only affected Ubuntu 26.04 LTS. (CVE-2026-11605)</p> <p>It was discovered that Bind incorrectly tracked memory usage in the DNS cache. A remote attacker could possibly use this issue to cause Bind to use memory beyond configured limits, leading to a denial of service. (CVE-2026-11622)</p> <p>It was discovered that Bind incorrectly handled signed wildcard records with label count discrepancies and RRSIG validation. A remote attacker could possibly use this issue to perform cache poisoning attacks. (CVE-2026-11721)</p> <p>It was discovered that Bind incorrectly handled certain CNAME and DNAME record orderings in the resolver.
