EUVD-2026-27493

CoreDNS is a DNS server written in Go. In versions prior to 1.14.3, the gRPC, QUIC, DoH, and DoH3 transport implementations incorrectly handle TSIG authentication. For gRPC and QUIC, the server checks whether the TSIG key name exists in the configuration but never calls dns.TsigVerify to validate...

EUVD-2026-27444

CoreDNS is a DNS server that chains plugins. In versions prior to 1.14.3, the tsig plugin can be bypassed on non-plain-DNS transports DoT, DoH, DoH3, DoQ, and gRPC because it trusts the transport writer's TsigStatus instead of performing verification itself. The DoH and DoH3 writer's TsigStatus...

CVE-2026-33190

CoreDNS TSIG authentication bypass vulnerability (CVE-2026-33190) affects versions prior to 1.14.3 on non-plain-DNS transports. The tsig plugin trusts the transport writer’s TsigStatus() instead of verifying TSIG itself, causing unauthenticated remote access over DoT, DoH, DoH3, DoQ, and gRPC. Do...

CoreDNS 安全漏洞

CoreDNS is a DNS server within the CoreDNS community. Versions of CoreDNS prior to 1.14.3 contained a security vulnerability. This vulnerability stemmed from the tsig plugin’s trust transfer writer, which relied on TsigStatus for verification instead of performing its own validation. This allowed...

CVE-2026-7668

A vulnerability was identified in MikroTik RouterOS 6.49.8. This vulnerability affects the function ASN1STRINGdata in the library nova/lib/www/scep.p of the component SCEP Endpoint. The manipulation of the argument transactionID/messageType leads to out-of-bounds read. The attack may be initiated...

CVE-2026-43041

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: replace qrtrtxflow radixtree with xarray to fix memory leak radixtreecreate allocates and links intermediate nodes into the tree one by one. If a subsequent allocation fails, the already-linked nodes remain in the tree...

CVE-2026-43041

CVE-2026-43041 concerns the Linux kernel: the irq/qrtr path (qrtr_tx_flow) used a radix_tree that could leak memory when intermediate nodes were linked but a subsequent allocation failed. The root cause was orphaned internal radix_tree nodes left behind because radix_tree_for_each_slot() only vis...

In the Linux kernel, the following vulnerability has been resolved: accel/qaic: Handle DBC deactivation if the owner went away When a DBC is released, the device sends a QAICTRANSDEACTIVATEFROMDEV transaction to the host over the QAICCONTROL MHI channel. QAIC handles this by calling...

glibc: glibc: Out-of-bounds write via TSIG record processing

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...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel, which stems from a failure to process a DBC de-activation transaction in the qaic driver after a user leaves, which could...

GHSA-28XX-PPPM-VQFF ydb-go-sdk's transactions are not committed using the `options.WithCommit()` option on last call `table.Transaction.Execute` in transaction

Impact Transactions were NOT committed despite the explicit options.WithCommit flag using table service client. Because of this, clients did not commit changes to the transaction, relying on the fact that the transaction commit was successful. This led in rare cases to a loss of data consistency...

GHSA-VP29-5652-4FW9 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...
