Inefficient candidate hostname parsing in crypto/x509

Go standard library crypto/x509; Red Hat Red Hat Ansible Automation Platform 2.5 for RHEL 8; Red Hat Red Hat Ansible Automation Platform 2.5 for RHEL 9; Red Hat Red Hat Ansible Automation Platform 2.6 for RHEL 10

(*x509.Certificate).VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name (SAN) entries. This caused strings.Split(host, ".") to execute repeatedly on the same input hostname. With a large DNS SAN list, verification c…

Invoking failure to reject ASCII-only Punycode-encoded labels in golang.org/x/net/idna

Go standard library net/http; Go standard library net/http/internal/http2; golang.org/x/net golang.org/x/net/idna; Red Hat Red Hat Ansible Automation Platform 2.5 for RHEL 8

The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error. This behavior can lead to privilege …

CVE-2026-32283

Unauthenticated TLS 1.3 KeyUpdate record can cause persistent connection retention and DoS in crypto/tls

Go standard library crypto/tls; Red Hat Cryostat 4 on RHEL 9; Red Hat Red Hat Ansible Automation Platform 2.5 for RHEL 8; Red Hat Red Hat Ansible Automation Platform 2.5 for RHEL 9

If one side of the TLS connection sends multiple key update messages post-handshake in a single record, the connection can deadlock, causing uncontrolled consumption of resources. This can lead to a denial of service. This only affects TLS 1.3.

Case-sensitive excludedSubtrees name constraints cause Auth Bypass in crypto/x509

Go standard library crypto/x509; Red Hat Cryostat 4 on RHEL 9; Red Hat HawtIO HawtIO 4.4.0; Red Hat Red Hat Enterprise Linux 10

When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issu…
