CVE-2026-50046

A use-after-free flaw was found in Unbound's DNS-over-TLS DoT forwarded query handling. A remote attacker can exploit a timing error during TLS handshake failures on a server under load to trigger a daemon crash, resulting in a Denial of Service DoS. Mitigation To mitigate this issue, avoid...

CVE-2026-46582

A flaw was found in Unbound, a Domain Name System DNS resolver. A remote attacker can exploit a vulnerability in how Unbound handles expired DNSSEC DNS Security Extensions records. By injecting a replayed wildcard record set, an attacker can cause Unbound to temporarily consider it secure, leadin...

CVE-2026-52863

A flaw was found in Unbound, a validating, recursive, and caching Domain Name System DNS resolver. When configured with specific modules and under heavy load, a memory corruption vulnerability can occur due to improper handling of view names during subquery processing. This issue could lead to a...

CVE-2026-56444

A Denial of Service DoS flaw exists in Unbound under specific serve-expired and discard-timeout configurations. By sending crafted queries, a remote attacker can exhaust an internal counter, causing the server to drop new legitimate client queries and degrade resolution services. Mitigation To...
