CVE-2026-81736

CVE-2026-81736 is a remote CPU denial of service in ISC BIND 9 . When a resolver has cached a tree of SVCB/HTTPS AliasMode records and receives a query for the root of that tree, it spends disproportionate CPU time constructing the response, leading to availability impact. Affected versions are 9...

EUVD-2026-80045

Netcore NR255-V version 1.5.130703 contains a stored cross-site scripting vulnerability in the DHCP dynamic IP display and ARP bind list display components handling hostname fields. A LAN-based attacker can inject malicious script through these hostname fields, which is later rendered by...

CVE-2026-77692: NULL Pointer Dereference

An attacker can cause named to abort by sending a crafted DNS-over-HTTPS request with a cryptographically invalid SIG0 record, and then closing the transport connection prematurely. This issue affects BIND 9 versions 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, and 9.20.9-S1 through 9.20.27-S1...

CVE-2026-80274: Reachable Assertion

If a BIND resolver sends a query for a DNSSEC-signed authoritative zone, and the authoritative server replies with a valid wildcard answer and signed NSEC3 proof, followed by an unsigned NSEC at the same owner name, it will trigger an unexpected program exit. This issue affects BIND 9 versions...

CVE-2026-77119: Origin Validation Error

A validly signed NSEC3 from an unrelated sibling zone may be accepted as an insecurity proof, downgrading a secure delegation and letting a forged unsigned answer through. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through...

CVE-2026-19667: Numeric Truncation Error

If an attacker-controlled authoritative server can produce a negative answer that is exactly 65536 bytes, then a flaw in named results in a negative cache entry of 0 bytes. When this entry is subsequently read, named aborts. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 throug...

CVE-2026-76163: Reachable Assertion

If BIND is loaded with a "named.conf" file that contains no global "options" block, an attacker can send a query of QTYPE TKEY which may cause an assertion failure and subsequent unexpected program exit. This issue affects BIND 9 versions 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, and...

CVE-2026-19668: Inefficient Algorithmic Complexity

A BIND recursive resolver may experience excessive resource consumption if it encounters large numbers of a particular kind of invalid DNSSEC record. Default limits on "max-records-per-type" and "max-types-per-name" help mitigate the exposure. This issue affects BIND 9 versions 9.11.0 through...

CVE-2026-81563: Missing Release of Memory after Effective Lifetime

A BIND resolver encountering an SVCB/HTTPS AliasMode record referencing 14 or more SVCB/HTTPS ServiceMode records may fail to properly deallocate internal resources. If this happens repeatedly, resource exhaustion will eventually prevent the resolver from performing new recursive lookups. This...
