SUSE CVE-2026-11622

A DNSSEC validating resolver that is under a random subdomain attack against a DNSSEC-signed zone can suffer from runaway memory usage. The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magnitude beyond the...

SUSE CVE-2026-11721

It is possible for an attacker's zone to respond to a query with an RRSIG that has a smaller number of labels than the zone in which the RRSIG is contained. This causes named to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cache poisoning. For...

SUSE CVE-2026-13321

The BIND resolver accepts validly-signed NSEC records where the "Next Domain Name" field points outside the signer's zone. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1...

SUSE CVE-2026-50252

In NLnet Labs Unbound 1.4.22 up to and including 1.25.1, UDP source port is randomized and intended to serve as a secret value that increases the entropy of DNS transactions. When resolver load balancing policies depend on the source port while their outcome is revealed this secrecy is undermined...

SUSE CVE-2026-55973

In NLnet Labs Unbound 1.23.0 up to and including 1.25.1, when 'dns-error-reporting: yes' is set, the EDNS Report-Channel option code 18 from the last upstream response is read and uses the option's length as the length of the agent domain. When a domain name check is performed on the agent domain...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The issue is a DNSSEC validation bypass where wildcard expansion proofs NSEC/NSEC3 records are accepted without signature validation when the wildcard answer is...

Linux Distros Unpatched Vulnerability : CVE-2026-56416

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In NLnet Labs Unbound up to and including version 1.25.1, when the validator builds the canonical RDATA form for an RRSIG-covered PX/RP/MINFO/SOA RRset, it...

Linux Distros Unpatched Vulnerability : CVE-2026-50248

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In NLnet Labs Unbound 1.7.0 up to and including 1.25.1, when an auth/rpz zone has a configured primary hostname that resolves to BOGUS A/AAAA, it is still...

Linux Distros Unpatched Vulnerability : CVE-2026-11605

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The issue is a resource exhaustion vulnerability associated with DNSSEC validation. BIND always validates all RRSIG records in an answer, even if they are not...

GHSA-MFG7-5GFP-C4W3 Netty: Memory Leak in DNS Record Decoder via Malformed Domain Names

Summary A memory leak can be caused in Netty's DNS codec by sending malicious DNS packets containing invalid domain names. Because the leak occurs incrementally per packet, sustained malicious requests will cause a gradual Denial of Service. Details Inside...

Missing Release of Resource after Effective Lifetime

Overview Affected versions of this package are vulnerable to Missing Release of Resource after Effective Lifetime in AbstractDnsRecord and DefaultDnsRecordDecoder, where a domain name that violates IDNA rules makes IDN.toASCII throw before the decoded ByteBuf is assigned to the record's content,...
