SUSE CVE-2026-5435
The deprecated functions nsprintrrf, nsprintrr and fpnquery in the GNU C Library version 2.2 and newer fail to enforce the caller-supplied buffer length, and can result in an out-of-bounds write when printing TSIG records...
Linux Distros Unpatched Vulnerability : CVE-2026-5435
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The deprecated functions nsprintrrf, nsprintrr and fpnquery in the GNU C Library version 2.2 and newer fail to enforce the caller-supplied buffer length, and ca...
CoreDNS has TSIG authentication bypass on gRPC and QUIC transports
Summary The gRPC, QUIC, DoH, and DoH3 transports in CoreDNS incorrectly handle TSIG authentication. For gRPC and QUIC, CoreDNS checks whether the TSIG key name exists in the config, but does not actually verify the TSIG HMAC. If the key name matches, tsigStatus remains nil and the tsig plugin...
Missing Authentication for Critical Function
Overview github.com/coredns/coredns/core/dnsserver is a package that implements all the interfaces from Caddy, so that CoreDNS can be a servertype plugin. Affected versions of this package are vulnerable to Missing Authentication for Critical Function via the tsig plugin on non-plain-DNS...
CoreDNS has TSIG authentication bypass on DoT, DoH, DoH3, DoQ, and gRPC
Summary CoreDNS' tsig plugin can be bypassed on non-plain-DNS transports because it trusts the transport writer's TsigStatus instead of performing verification itself. In the attached PoC, plain DNS/TCP correctly rejects an invalid TSIG NOTAUTH, while the same invalid-TSIG request is accepted ove...

CVE-2026-5435
A flaw was found in glibc, the GNU C Library. Specifically, deprecated functions responsible for printing TSIG Transaction Signature records fail to properly manage memory buffers. This oversight can lead to an out-of-bounds write when processing specially crafted TSIG records. An attacker could...

CVE-2026-5435
CVE-2026-5435 affects the GNU C Library (glibc) where deprecated functions for printing TSIG records (ns_printrrf, ns_printrr, fp_nquery) do not respect caller buffer lengths, enabling an out-of-bounds write in versions 2.2 and newer. This can lead to a denial of service and, in some scenarios, p...
