| Applications and libraries which misuse connection.serverAuthenticate (via callback field ServerConfig.PublicKeyCallback) may be susceptible to an authorization bypass. The documentation for ServerConfig.PublicKeyCallback says that "A call to this function does not guarantee that the key offered is in fact used to authenticate." Specifically, the SSH protocol allows clients to inquire about whether a public key is acceptable before proving control of the corresponding private key. PublicKeyCallback may be called with multiple keys, and the order in which the keys were provided cannot be used to infer which key the client successfully authenticated with, if any. Some applications, which store the key(s) passed to PublicKeyCallback (or derived information) and make security relevant determinations based on it once the connection is established, may make incorrect assumptions. For example, an attacker may send public keys A and B, and then authenticate with A. PublicKeyCallback would be called only twice, first with A and then with B. A vulnerable application may then make authorization decisions based on key B for which the attacker does not actually control the private key. Since this API is widely misused, as a partial mitigation golang.org/x/cry...@v0.31.0 enforces the property that, when successfully authenticating via public key, the last key passed to ServerConfig.PublicKeyCallback will be the key used to authenticate the connection. PublicKeyCallback will now be called multiple times with the same key, if necessary. Note that the client may still not control the last key passed to PublicKeyCallback if the connection is then authenticated with a different method, such as PasswordCallback, KeyboardInteractiveCallback, or NoClientAuth. Users should be using the Extensions field of the Permissions return value from the various authentication callbacks to record data associated with the authentication attempt instead of referencing external state. Once the connection is established the state corresponding to the successful authentication attempt can be retrieved via the ServerConn.Permissions field. Note that some third-party libraries misuse the Permissions type by sharing it across authentication attempts; users of third-party libraries should refer to the relevant projects for guidance. | ||||
| CVE-2024-24791 | 2 Go Standard Library, Redhat | 20 Net\/http, Amq Streams, Ceph Storage and 17 more | 2026-04-15 | 7.5 High |
| The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an "Expect: 100-continue" header with a non-informational (200 or higher) status. This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail. An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending "Expect: 100-continue" requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail. | ||||
| CVE-2024-43803 | 1 Redhat | 1 Openshift | 2026-04-15 | 4.9 Medium |
| The Bare Metal Operator (BMO) implements a Kubernetes API for managing bare metal hosts in Metal3. The `BareMetalHost` (BMH) CRD allows the `userData`, `metaData`, and `networkData` for the provisioned host to be specified as links to Kubernetes Secrets. There are fields for both the `Name` and `Namespace` of the Secret, meaning that versions of the baremetal-operator prior to 0.8.0, 0.6.2, and 0.5.2 will read a `Secret` from any namespace. A user with access to create or edit a `BareMetalHost` can thus exfiltrate a `Secret` from another namespace by using it as e.g. the `userData` for provisioning some host (note that this need not be a real host, it could be a VM somewhere). BMO will only read a key with the name `value` (or `userData`, `metaData`, or `networkData`), so that limits the exposure somewhat. `value` is probably a pretty common key though. Secrets used by _other_ `BareMetalHost`s in different namespaces are always vulnerable. It is probably relatively unusual for anyone other than cluster administrators to have RBAC access to create/edit a `BareMetalHost`. This vulnerability is only meaningful, if the cluster has users other than administrators and users' privileges are limited to their respective namespaces. The patch prevents BMO from accepting links to Secrets from other namespaces as BMH input. Any BMH configuration is only read from the same namespace only. The problem is patched in BMO releases v0.7.0, v0.6.2 and v0.5.2 and users should upgrade to those versions. Prior upgrading, duplicate the BMC Secrets to the namespace where the corresponding BMH is. After upgrade, remove the old Secrets. As a workaround, an operator can configure BMO RBAC to be namespace scoped for Secrets, instead of cluster scoped, to prevent BMO from accessing Secrets from other namespaces. | ||||
| CVE-2024-21538 | 2 Cross-spawn, Redhat | 12 Cross-spawn, Advanced Cluster Security, Discovery and 9 more | 2026-04-15 | 7.5 High |
| Versions of the package cross-spawn before 6.0.6, from 7.0.0 and before 7.0.5 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU usage and crash the program by crafting a very large and well crafted string. | ||||
| CVE-2024-22189 | 1 Redhat | 4 Acm, Ansible Automation Platform, Openshift and 1 more | 2026-04-15 | 7.5 High |
| quic-go is an implementation of the QUIC protocol in Go. Prior to version 0.42.0, an attacker can cause its peer to run out of memory sending a large number of `NEW_CONNECTION_ID` frames that retire old connection IDs. The receiver is supposed to respond to each retirement frame with a `RETIRE_CONNECTION_ID` frame. The attacker can prevent the receiver from sending out (the vast majority of) these `RETIRE_CONNECTION_ID` frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer's RTT estimate. Version 0.42.0 contains a patch for the issue. No known workarounds are available. | ||||
| CVE-2024-34155 | 1 Redhat | 15 Ceph Storage, Cost Management, Cryostat and 12 more | 2026-04-15 | 4.3 Medium |
| Calling any of the Parse functions on Go source code which contains deeply nested literals can cause a panic due to stack exhaustion. | ||||
| CVE-2024-34156 | 2 Go Standard Library, Redhat | 19 Encoding\/gob, Advanced Cluster Security, Ceph Storage and 16 more | 2026-04-15 | 7.5 High |
| Calling Decoder.Decode on a message which contains deeply nested structures can cause a panic due to stack exhaustion. This is a follow-up to CVE-2022-30635. | ||||
| CVE-2024-7387 | 1 Redhat | 1 Openshift | 2026-04-15 | 9.1 Critical |
| A flaw was found in openshift/builder. This vulnerability allows command injection via path traversal, where a malicious user can execute arbitrary commands on the OpenShift node running the builder container. When using the “Docker” strategy, executable files inside the privileged build container can be overridden using the `spec.source.secrets.secret.destinationDir` attribute of the `BuildConfig` definition. An attacker running code in a privileged container could escalate their permissions on the node running the container. | ||||
| CVE-2024-12705 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-04-15 | 7.5 High |
| Clients using DNS-over-HTTPS (DoH) can exhaust a DNS resolver's CPU and/or memory by flooding it with crafted valid or invalid HTTP/2 traffic. This issue affects BIND 9 versions 9.18.0 through 9.18.32, 9.20.0 through 9.20.4, 9.21.0 through 9.21.3, and 9.18.11-S1 through 9.18.32-S1. | ||||
| CVE-2024-24786 | 2 Golang, Redhat | 24 Go, Acm, Ceph Storage and 21 more | 2026-04-15 | 7.5 High |
| The protojson.Unmarshal function can enter an infinite loop when unmarshaling certain forms of invalid JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any value, or when the UnmarshalOptions.DiscardUnknown option is set. | ||||
| CVE-2024-52615 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-04-15 | 5.3 Medium |
| A flaw was found in Avahi-daemon, which relies on fixed source ports for wide-area DNS queries. This issue simplifies attacks where malicious DNS responses are injected. | ||||
| CVE-2024-44082 | 1 Redhat | 3 Openshift, Openshift Ironic, Openstack | 2026-04-15 | 4.3 Medium |
| In OpenStack Ironic before 26.0.1 and ironic-python-agent before 9.13.1, there is a vulnerability in image processing, in which a crafted image could be used by an authenticated user to exploit undesired behaviors in qemu-img, including possible unauthorized access to potentially sensitive data. The affected/fixed version details are: Ironic: <21.4.3, >=22.0.0 <23.0.2, >=23.1.0 <24.1.2, >=25.0.0 <26.0.1; Ironic-python-agent: <9.4.2, >=9.5.0 <9.7.1, >=9.8.0 <9.11.1, >=9.12.0 <9.13.1. | ||||
| CVE-2025-29781 | 1 Redhat | 1 Openshift | 2026-04-15 | 6.5 Medium |
| The Bare Metal Operator (BMO) implements a Kubernetes API for managing bare metal hosts in Metal3. Baremetal Operator enables users to load Secret from arbitrary namespaces upon deployment of the namespace scoped Custom Resource `BMCEventSubscription`. Prior to versions 0.8.1 and 0.9.1, an adversary Kubernetes account with only namespace level roles (e.g. a tenant controlling a namespace) may create a `BMCEventSubscription` in his authorized namespace and then load Secrets from his unauthorized namespaces to his authorized namespace via the Baremetal Operator, causing Secret Leakage. The patch makes BMO refuse to read Secrets from other namespace than where the corresponding BMH resource is. The patch does not change the `BMCEventSubscription` API in BMO, but stricter validation will fail the request at admission time. It will also prevent the controller reading such Secrets, in case the BMCES CR has already been deployed. The issue exists for all versions of BMO, and is patched in BMO releases v0.9.1 and v0.8.1. Prior upgrading to patched BMO version, duplicate any existing Secret pointed to by `BMCEventSubscription`'s `httpHeadersRef` to the same namespace where the corresponding BMH exists. After upgrade, remove the old Secrets. As a workaround, the operator can configure BMO RBAC to be namespace scoped, instead of cluster scoped, to prevent BMO from accessing Secrets from other namespaces, and/or use `WATCH_NAMESPACE` configuration option to limit BMO to single namespace. | ||||
| CVE-2025-61663 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-04-15 | 4.9 Medium |
| A vulnerability has been identified in the GRUB2 bootloader's normal command that poses an immediate Denial of Service (DoS) risk. This flaw is a Use-after-Free issue, caused because the normal command is not properly unregistered when the module is unloaded. An attacker who can execute this command can force the system to access memory locations that are no longer valid. Successful exploitation leads directly to system instability, which can result in a complete crash and halt system availability. Impact on the data integrity and confidentiality is also not discarded. | ||||
| CVE-2025-4382 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-04-15 | 5.9 Medium |
| A flaw was found in systems utilizing LUKS-encrypted disks with GRUB configured for TPM-based auto-decryption. When GRUB is set to automatically decrypt disks using keys stored in the TPM, it reads the decryption key into system memory. If an attacker with physical access can corrupt the underlying filesystem superblock, GRUB will fail to locate a valid filesystem and enter rescue mode. At this point, the disk is already decrypted, and the decryption key remains loaded in system memory. This scenario may allow an attacker with physical access to access the unencrypted data without any further authentication, thereby compromising data confidentiality. Furthermore, the ability to force this state through filesystem corruption also presents a data integrity concern. | ||||
| CVE-2024-2357 | 1 Redhat | 4 Enterprise Linux, Openshift, Rhel E4s and 1 more | 2026-04-15 | 6.5 Medium |
| The Libreswan Project was notified of an issue causing libreswan to restart under some IKEv2 retransmit scenarios when a connection is configured to use PreSharedKeys (authby=secret) and the connection cannot find a matching configured secret. When such a connection is automatically added on startup using the auto= keyword, it can cause repeated crashes leading to a Denial of Service. | ||||
| CVE-2023-45288 | 3 Go Standard Library, Golang, Redhat | 33 Net\/http, Http2, Acm and 30 more | 2026-04-15 | 7.5 High |
| An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection. | ||||
| CVE-2024-24784 | 2 Go Standard Library, Redhat | 14 Net\/mail, Advanced Cluster Security, Ceph Storage and 11 more | 2026-04-15 | 7.5 High |
| The ParseAddressList function incorrectly handles comments (text within parentheses) within display names. Since this is a misalignment with conforming address parsers, it can result in different trust decisions being made by programs using different parsers. | ||||
| CVE-2024-7128 | 1 Redhat | 1 Openshift | 2026-04-15 | 5.3 Medium |
| A flaw was found in the OpenShift console. Several endpoints in the application use the authHandler() and authHandlerWithUser() middleware functions. When the default authentication provider ("openShiftAuth") is set, these functions do not perform any authentication checks, relying instead on the targeted service to handle authentication and authorization. This issue leads to various degrees of data exposure due to a lack of proper credential verification. | ||||
