Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the container images for Red Hat OpenShift Container Platform 4.22.14. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHSA-2026:66356 Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes: https://docs.redhat.com/en/documentation/openshift_container_platform/4.22/html/release_notes/ Security Fix(es): * curl: curl: Insecure connection establishment due to TLS configuration mismatch (CVE-2026-8286) * curl: curl: Man-in-the-middle attack via SSH host key bypass (CVE-2026-9547) * bind: bind9: Cache poisoning via label count discrepancy, RRSIG, wildcards (CVE-2026-11721) * sqlite: SQLite: Arbitrary code execution and crash via heap-based buffer overflow in FTS5 (CVE-2026-11824) * bind: bind9: Unexpected exit with NSEC and NSEC3 both present (CVE-2026-13204) * dracut: dracut: root code execution via unescaped error message written to sourced emergency hook script in die() (CVE-2026-15816) * kernel: KVM: nSVM: Always use vmcb01 in VMLOAD/VMSAVE emulation (CVE-2026-43133) * unbound: Unbound: Denial of Service via malformed EDNS Report-Channel option (CVE-2026-55973) * glib: off-by-one error in glib/gkeyfile.c via "g_key_file_get_locale_string_list" (CVE-2026-58014) * glib: path traversal in glib/gio/gdbusauthmechanismsha1.c via keyring_lookup_entry and mechanism_client_data_receive (CVE-2026-58015) * kbd: Local privilege escalation in openvt via incorrect process owner verification allowing passwordless root login (CVE-2026-72693) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. All OpenShift Container Platform 4.22 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.redhat.com/en/documentation/openshift_container_platform/4.22/html-single/updating_clusters/index#updating-cluster-cli.

Red Hat Update Infrastructure (RHUI) container images are based on the latest RHUI RPM packages and the ubi9 or ubi9-init base images. This release updates to the latest version.

Red Hat Discovery, also known as Discovery, is an inspection and reporting tool that finds, identifies, and reports environment data, or facts, such as the number of physical and virtual systems on a network, their operating systems, and relevant configuration data stored within them. Discovery also identifies and reports more detailed facts for some versions of key Red Hat packages and products that it finds in the network.

A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang.

An off-by-one error exists in the GLib library within the g_key_file_get_locale_string_list function when loading a key file with an empty value. This flaw can cause an out-of-bounds access of one byte, potentially leading to a denial of service if the access crosses a page boundary. The vulnerability has a CVSS score of 7.3, indicating high severity. A fix is available as detailed in the Red Hat advisory RHSA-2026:49512.

An off-by-one error in the gvs_tuple_is_normal function of GLib's gvariant-serialiser.c file causes an out-of-bounds read of one byte. This flaw can lead to minor information disclosure and denial of service if the read crosses a page boundary. The vulnerability affects GLib versions from 2.68.0 up to but not including 2.70.1. A fix is available and has been issued by Red Hat.

A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary.

GLib provides the core application building blocks for libraries and applications written in C. It provides the core object system used in GNOME, the main loop implementation, and a large set of utility functions for strings and common data structures. Security Fix(es): * glib: GLib: Buffer underflow in GVariant parser leads to heap corruption (CVE-2025-14087) * glib: Integer Overflow in GLib GIO Attribute Escaping Causes Heap Buffer Overflow (CVE-2025-14512) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings.
