| CVE-2026-92856 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-11-09 | 4.9 Medium |
| A flaw was found in the SAML brokering component of Keycloak, an identity and access management solution. The issue occurs when Keycloak acts as an intermediary between an upstream identity provider and downstream services. Keycloak fails to respect specific security instructions called ProxyRestrictions in the login messages it receives. This allows a user to log into downstream services even when the original identity provider explicitly forbade further sharing of the login session. As a result, users can bypass security boundaries intended to limit where their identity can be used. | ||||

| A flaw was found in the SAML 1.1 assertion parser of Keycloak, a tool used for identity and access management. The issue occurs when the parser handles a specific element called AuthorityBinding within an authentication statement. Due to an incomplete fix for a previous vulnerability, the parser can enter an infinite loop that consumes all available memory, causing the entire Keycloak service to crash and become unavailable to users. | ||||

| Issue summary: Calling the OpenSSL API function SSL_free_buffers may cause memory to be accessed that was previously freed in some situations Impact summary: A use after free can have a range of potential consequences such as the corruption of valid data, crashes or execution of arbitrary code. However, only applications that directly call the SSL_free_buffers function are affected by this issue. Applications that do not call this function are not vulnerable. Our investigations indicate that this function is rarely used by applications. The SSL_free_buffers function is used to free the internal OpenSSL buffer used when processing an incoming record from the network. The call is only expected to succeed if the buffer is not currently in use. However, two scenarios have been identified where the buffer is freed even when still in use. The first scenario occurs where a record header has been received from the network and processed by OpenSSL, but the full record body has not yet arrived. In this case calling SSL_free_buffers will succeed even though a record has only been partially processed and the buffer is still in use. The second scenario occurs where a full record containing application data has been received and processed by OpenSSL but the application has only read part of this data. Again a call to SSL_free_buffers will succeed even though the buffer is still in use. While these scenarios could occur accidentally during normal operation a malicious attacker could attempt to engineer a stituation where this occurs. We are not aware of this issue being actively exploited. The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. | ||||
| CVE-2026-96453 | 1 Redhat | 7 Amq Broker, Build Keycloak, Jboss Enterprise Application Platform and 4 more | 2026-11-09 | 8 High |
| A flaw was found in the Keycloak Admin CLI kcadm tool, which is used by administrators to manage Keycloak servers from the command line. When a custom truststore is provided to verify the server identity, the tool incorrectly accepts any self-signed certificate as long as the hostname matches. This allows a network attacker to impersonate the Keycloak server, steal administrative credentials, and perform unauthorized management actions. | ||||
| CVE-2026-12542 | 2 Redhat, Theforeman | 5 Enterprise Linux, Satellite, Satellite Capsule and 2 more | 2026-11-09 | 5.3 Medium |
| A flaw was found in Foreman. The foreman-tail utility is vulnerable to OS command injection due to the unsafe use of the eval command. The script takes user-supplied arguments and incorporates them directly into a string that is then executed by eval to expand file paths. Because the input is not sanitized or quoted, a local attacker can inject shell metacharacters (e.g., ;, &, |) to execute arbitrary system commands. | ||||
| CVE-2026-121601 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Rhel Els | 2026-11-09 | 6.1 Medium |
| A flaw was found in GStreamer's MXF demuxer plugin (gst-plugins-bad). When processing a specially crafted MXF media file, the demuxer indexes its internal delta-entry and slice-offset tables using values from the file without validating that they are within the bounds of the allocated arrays. A local attacker who tricks a user into opening a malicious MXF file can cause the application to crash (denial of service) and may be able to read limited amounts of heap memory adjacent to the affected arrays. | ||||
| CVE-2026-112208 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-09 | 8.1 High |
| A flaw was found in the Organization identity-first login flow of the Keycloak authentication server. Keycloak is an open-source identity and access management solution used to secure modern applications and services. The issue occurs when an attacker who belongs to multiple organizations initiates a login and then switches to a registration or password reset path. During this process, a flag indicating a successful login is not properly cleared when the user is removed from the session. An attacker can then provide a victim's username, and the system incorrectly treats the stale flag as proof of the victim's identity. This allows the attacker to bypass authentication and gain full access to the victim's account and connected applications. | ||||

| Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers. | ||||
| CVE-2026-115207 | 2 Red Hat, Redhat | 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more | 2026-11-09 | 5.5 Medium |
| A flaw was found in GNU patch. An attacker can achieve arbitrary file creation outside the intended working directory by enticing a user or automated workflow to apply a specially crafted patch file. Due to missing validation during automatic patch reversal, absolute file paths in patch headers are accepted rather than rejected. Consequently, the utility can create files in arbitrary locations with the permissions of the executing user. | ||||
| CVE-2026-12080 | 2 Qemu, Redhat | 5 Qemu, Enterprise Linux, Enterprise Linux Nvidia and 2 more | 2026-11-09 | 7.3 High |
| A flaw was found in the QEMU Guest Agent (qga). A local unprivileged user can exploit a vulnerability in the guest-ssh-add-authorized-keys command handler by manipulating symbolic links. This can occur either through a deterministic directory-symlink bypass or a Time-of-Check to Time-of-Use (TOCTOU) file-symlink race. Successful exploitation allows the attacker to gain ownership of arbitrary root-owned files or directories, leading to root access. This vulnerability requires an external management layer (e.g., libvirt) to trigger the affected code path. | ||||
| CVE-2024-4603 | 3 Netapp, Openssl, Redhat | 40 500f, 500f Firmware, 8300 and 37 more | 2026-11-09 | 5.3 Medium |
| Issue summary: Checking excessively long DSA keys or parameters may be very slow. Impact summary: Applications that use the functions EVP_PKEY_param_check() or EVP_PKEY_public_check() to check a DSA public key or DSA parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. The functions EVP_PKEY_param_check() or EVP_PKEY_public_check() perform various checks on DSA parameters. Some of those computations take a long time if the modulus (`p` parameter) is too large. Trying to use a very large modulus is slow and OpenSSL will not allow using public keys with a modulus which is over 10,000 bits in length for signature verification. However the key and parameter check functions do not limit the modulus size when performing the checks. An application that calls EVP_PKEY_param_check() or EVP_PKEY_public_check() and supplies a key or parameters obtained from an untrusted source could be vulnerable to a Denial of Service attack. These functions are not called by OpenSSL itself on untrusted DSA keys so only applications that directly call these functions may be vulnerable. Also vulnerable are the OpenSSL pkey and pkeyparam command line applications when using the `-check` option. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are affected by this issue. | ||||
| CVE-2026-82976 | 1 Redhat | 2 Openshift, Openshift Container Platform | 2026-11-09 | 7.1 High |
| A flaw was found in the image-customization-controller used in OpenShift's bare metal provisioning stack. The controller registers an HTTP file server on port 8084 with no authentication. The custom imageFileSystem implementation exposes a browsable HTML directory listing of all registered images at the root path. The only access control on per-host images is the random UUID filename; the directory listing discloses those UUIDs to any caller on the provisioning network. Each served image embeds an Ignition config containing the base64-encoded cluster pull secret, optional IRONIC_RAMDISK_SSH_KEY, proxy settings, and per-host NetworkManager keyfiles. An adjacent network attacker can enumerate all image UUIDs via directory listing, download any image, extract the embedded Ignition config, and recover the cluster pull secret and SSH key. ### Evidence **pkg/imagehandler/imagefilesystem.go — root directory is browsable and enumerates all UUID image names** ```go func (f *imageFileSystem) Readdir(n int) ([]fs.FileInfo, error) { f.mu.Lock() defer f.mu.Unlock() result := []fs.FileInfo{} for _, im := range f.images { result = append(result, im) } return result, nil } func (f *imageFileSystem) Open(name string) (http.File, error) { f.log.Info("Open", "path", name) if name == "/" { return f, nil } ... ``` **cmd/controller/main.go — file server bound on all interfaces without auth or TLS** ```go http.Handle("/", http.FileServer(imageServer.FileSystem())) go func() { server := &http.Server{ Addr: imagesBindAddr, // default ":8084" ReadHeaderTimeout: 5 * time.Second, } err := server.ListenAndServe() ``` **pkg/ignition/service_config.go:94-100 — pull secret is embedded in every served image** ```go func (b *ignitionBuilder) authFile() ignition_config_types_32.File { source := "data:;base64," + strings.TrimSpace(b.ironicAgentPullSecret) return ignition_config_types_32.File{ Node: ignition_config_types_32.Node{Path: "/etc/authfile.json"}, ... ``` ### Attack Pattern Adjacent provisioning-network client → GET / lists UUID image names → download ISO/initramfs → extract embedded Ignition → recover cluster pull secret and SSH key. | ||||
| CVE-2026-119610 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Rhel Els | 2026-11-09 | 8.2 High |
| A flaw was found in GStreamer's gst-plugins-good, specifically in the H.264 RTP depayloader element. When processing MTAP16 or MTAP24 multi-time aggregation RTP packets, a signed/unsigned integer conversion error causes the remaining-length counter to underflow to a large positive value when the packet is truncated. This allows a remote, unauthenticated attacker to trigger an out-of-bounds heap read of up to approximately 64 KiB of process memory by sending a single malformed RTP packet. Successful exploitation can crash the receiving GStreamer pipeline (denial of service), and in relay or transcoding deployments where output is accessible to the attacker, may expose adjacent heap contents. | ||||
| CVE-2026-120830 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-11-09 | 7.4 High |
| A flaw was found in libslirp in icmp_forward_error(). When building an ICMP error response, the length of the quoted original IPv4 packet was taken from the IP header without clamping it to the actual buffer length. A truncated or malformed packet could cause an out-of-bounds heap read, leaking host memory into the ICMP error packet returned to a guest or container. | ||||
| CVE-2026-101296 | 3 Apache, Apache Software Foundation, Redhat | 4 Apache Tomcat, Tomcat, Tomcat and 1 more | 2026-11-09 | 8.1 High |
| A missing critical step in authentication vulnerability in Apache Tomcat when the JNDI realm was configured with with a non GSSAPI SASL authentication mechanism allowed attackers to authenticate without providing the correct password. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.26, from 10.1.0-M1 through 10.1.60, from 9.0.0.M1 through 9.0.122. The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.27, 10.1.61 or 9.0.123, which fix the issue. | ||||
| CVE-2026-18942 | 2 Red Hat, Redhat | 2 Red Hat Openshift Ai (rhoai), Openshift Ai | 2026-11-09 | 5.5 Medium |
| A flaw was found in the Feast operator. A malicious tenant could inject arbitrary code into their feature repository. This code would be executed by an automated process with elevated privileges, allowing the tenant to steal sensitive credentials. This could lead to a direct escalation of privileges, granting the tenant administrative control over the Kubernetes cluster. | ||||
| CVE-2026-120984 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-09 | 9.1 Critical |
| A flaw was found in the Keycloak server's client management component. When a client is created or imported with authorization services enabled, the system fails to properly clear an internal session attribute used during the setup process. This allows an authenticated attacker with client management permissions to bypass security controls and upload a malicious JavaScript policy, which is then executed on the server when an authorization request is made. Successful exploitation could allow the attacker to run arbitrary code on the server, potentially compromising the entire system. | ||||
| CVE-2026-88833 | 2 Busybox, Redhat | 3 Busybox, Hummingbird, Rhel Els | 2026-11-09 | 6.5 Medium |
| A flaw was found in BusyBox's udhcpc DHCP client. When processing raw DHCP packets, the client replaces the validated packet length with an attacker-controlled value from the IP header without re-validating the minimum size. This leads to an integer underflow when subtracting header sizes, causing a subsequent memory copy with a massively oversized length. An attacker on the same network segment can send a specially crafted packet to crash the DHCP client, resulting in denial of service and loss of network connectivity. | ||||
| CVE-2026-13732 | 1 Redhat | 9 Cost Management On Premise, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-11-09 | 7 High |
| A flaw was found in GDB's STABS debug format parser. The read_member_functions() function in gdb/stabsread.c contains a linked list removal bug in the code that separates destructor and non-destructor member functions of C++ classes. The bug causes the destructor entries to remain in the main function list while the list length counter is decremented, resulting in an out-of-bounds write when the function list is copied to its final allocated array. An attacker can craft an ELF binary with malicious .stab and .stabstr sections that triggers this out-of-bounds write when a user opens the file in GDB and performs any symbol-inspection operation such as setting a breakpoint. The inferior process does not need to be executed. Under controlled conditions, this was demonstrated to achieve execution of arbitrary commands within the GDB process. | ||||
