A flaw was found in the net/url package in the Go standard library. The package does not enforce a limit on the number of unique query parameters it parses. A Go application using the net/http.Request.ParseForm method will try to process all parameters provided in the request. A specially crafted HTTP request containing a massive number of query parameters will cause the application to consume an excessive amount of memory, eventually causing the application to crash or become unresponsive, resulting in a denial of service.

Threats
Impact
Important
The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid.

9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in the `crypto/x509` package of `golang`. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name (SAN) entries. The certificate verification process, specifically the `VerifyHostname` function, incurs excessive computational overhead due to repeated string operations when processing these entries. This can lead to a significant performance degradation or unresponsiveness of systems validating such certificates.

Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in the Go standard library packages `crypto/x509` and `crypto/tls`. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being performed. This can result in a denial of service (DoS) condition, making the affected system or application unavailable to legitimate users.
7.5 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in the `crypto/tls` package within the Go (golang) standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock, leading to uncontrolled consumption of resources and ultimately a denial of service (DoS).
7.5 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in the `net` package of Go (golang), specifically when using the `LookupCNAME` function with the `cgo` DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name (CNAME) response. This can trigger a double-free of C memory, leading to a crash and a Denial of Service (DoS) for the affected application.
7.5 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in the `encoding/asn1` package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One (ASN.1) structure, leading to excessive recursion during the `Unmarshal` operation. This could result in stack exhaustion and a Denial of Service (DoS) condition.
7.5 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname (for example, xn--example-.com returns example.com instead of an error). Applications that validate the ASCII form then convert to Unicode may grant access to a restricted hostname the ASCII check would have rejected.
8.2 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in the `net/http` component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the `ReadHeaderTimeout` is not correctly applied during this process. This oversight could allow a remote attacker to maintain open connections indefinitely, potentially leading to a Denial of Service (DoS) by exhausting server resources.
7.5 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in the `html/template` component of Go (golang). Pathological inputs could prematurely close an unescaped forward slash ('/'), allowing an attacker to inject arbitrary content. This could lead to Cross-Site Scripting (XSS), where malicious scripts are executed in a user's browser, potentially compromising user data or actions.
8.1 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in `net/url`, a component of `golang`. This vulnerability arises when resolving relative paths that contain numerous parent directory ('..') segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory allocation. This can result in a Denial of Service (DoS) due to resource exhaustion.
7.5 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in the `crypto/tls` package, part of `golang`. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service (DoS) condition.
7.5 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in etcd, a distributed key-value store. A remote attacker can exploit this by opening numerous TCP connections to an etcd TLS listener without completing the TLS handshake. This action causes the `tlsListener.acceptLoop` to spawn an unbounded number of goroutines, which consume excessive memory. This resource exhaustion leads to a Denial of Service (DoS) for the etcd cluster and, consequently, for the Kubernetes control plane it supports.
7.5 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in the Go net/http package. This flaw allows a remote attacker to cause a Denial of Service (DoS) by triggering excessive CPU consumption on an affected client or server. By opening a large number of HTTP/2 streams and repeatedly sending small configuration (SETTINGS) frames that modify window sizes, an attacker forces the system into intensive state processing. This resource exhaustion degrades performance and can render the service unresponsive.
7.5 (High)
Affected products
Fixed
9 products, the same list as for
CVE-2025-61726
Threats
Impact
Important
A flaw was found in Go's crypto/x509 package. The certificate verification process fails to block trust in intermediate certificates associated with a compromised Certificate Authority (CA). A remote attacker presenting a certificate signed by these intermediate authorities can impersonate legitimate servers during secure connections. This flaw can enable an attacker to conduct a man-in-the-middle (MitM) attack to intercept or alter confidential communications.

"text": "A flaw was found in the Go standard library crypto/x509 package. When verifying a TLS certificate hostname, VerifyHostname processed each DNS Subject Alternative Name (SAN) entry in a loop and repeatedly split the candidate hostname on \".\" characters. For certificates with a very large DNS SAN list, CPU use could grow quadratically with the number of SAN entries and hostname labels. Because hostname verification runs before the certificate chain is built, this overhead can occur even when the certificate is not trusted.\n\nRed Hat rates this issue as Important.
