CVE-2026-104044 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-08 6.2 Medium
A flaw was found in sssd. A local attacker can trigger a Denial of Service (DoS) by sending a specially crafted Pluggable Authentication Module (PAM) request when passkey authentication is enabled. Due to a missing state validation check in passkey Kerberos handling, the PAM responder dereferences an uninitialized pointer and crashes. This failure disrupts authentication services on the host.
CVE-2026-104035 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-08 5.5 Medium
A flaw was found in SSSD. An issue in the Kerberos Credential Manager (KCM) responder allows a local user to cause a Denial of Service (DoS) by maintaining a persistent connection and repeatedly storing and destroying credentials. Because the service fails to release cached objects from memory when credentials are removed, memory consumption grows continuously, ultimately exhausting available memory and rendering the service unresponsive.
CVE-2026-104042 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-07 5.5 Medium
A flaw was found in sssd. A local attacker can cause a Denial of Service (DoS) by sending a crafted Pluggable Authentication Module (PAM) request containing a zero-length authentication token to the responder socket. Due to missing input validation, the service attempts to read beyond buffer boundaries when processing the token, causing the PAM responder to crash.
CVE-2026-104038 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-07 5.9 Medium
A flaw was found in sssd. A remote attacker can cause a denial of service (DoS) by submitting a certificate that lacks an expected Security Identifier (SID) extension. In deployments configured with SID-based certificate mapping rules, the service fails to verify the presence of the extension before processing it, causing the process to crash during authentication or lookup operations.
CVE-2026-104033 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-07 5.4 Medium
A flaw was found in SSSD. When configured to enforce account expiration using LDAP (Lightweight Directory Access Protocol) shadow attributes, SSSD fails to treat an expiration value of zero as an expired account. A user with valid credentials for an expired account can exploit this flaw to bypass access controls and authenticate to the system. This allows unauthorized access to persist after the account was intended to be deactivated.
CVE-2026-90996 2 Fedoraproject, Redhat 4 Sssd, Enterprise Linux, Openshift and 1 more 2026-10-07 4 Medium
A flaw was found in sssd. A local unprivileged user could send a specially crafted request with a zero-length body to the Network Security Services (NSS) responder. This could lead to a denial-of-service condition, causing the NSS responder to become unstable or terminate. This vulnerability affects the availability of the system responder.
CVE-2026-87114 1 Redhat 4 Openshift, Openshift Container Platform, Pdrive Lightspeed and 1 more 2026-10-07 7.1 High
A flaw was found in kube-compare. When processing a 'container://' reference path, the tool incorrectly executes an untrusted container image's entrypoint instead of merely extracting data from a stopped container. This allows a remote attacker to achieve arbitrary code execution on the operator's workstation. If the Docker daemon requires elevated privileges, the untrusted code may execute with root-mediated daemon privileges, posing a significant security risk.
CVE-2026-90462 3 Fedoraproject, Redhat, Sssd 5 Sssd, Enterprise Linux, Openshift and 2 more 2026-10-07 5.4 Medium
A flaw was found in SSSD. When configured with the LDAP access provider and `ldap_access_order` including `ppolicy` or `lockout`, a fail-open condition in the LDAP ppolicy access check can occur if a user lookup returns zero results. This can incorrectly return success and cache an allow decision, permitting continued authorization for a deleted or deprovisioned user. A remote attacker with prior valid account context could exploit this to maintain access to information and potentially make limited modifications to resources that should no longer be available.
CVE-2026-104034 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-06 4.7 Medium
A flaw was found in SSSD. A use-after-free vulnerability exists in the Kerberos Credential Manager (KCM) responder during Kerberos ticket-granting ticket (TGT) renewal, where a deferred callback accesses memory that has already been released. An authenticated local user with a renewable Kerberos ticket can trigger this issue on systems configured with KCM renewal, causing the KCM responder service to crash and resulting in a Denial of Service (DoS).
CVE-2026-104036 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-06 5.8 Medium
A flaw was found in SSSD's NFS idmap plugin. When retrieving cached user or group names, the plugin detects if an entry exceeds the destination buffer size but fails to abort before copying data. A local attacker can trigger this vulnerability by requesting identity lookups that resolve to oversized cached entries, resulting in an out-of-bounds write. This flaw primarily leads to a Denial of Service (DoS) by crashing the identity mapping service, and may also corrupt adjacent process memory.
CVE-2026-92821 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-06 6.8 Medium
A flaw was found in SSSD. When configured to evaluate password expiration warnings before restrictive access rules in LDAP (Lightweight Directory Access Protocol) environments, an expired-password warning terminates rule evaluation early and treats the access request as successful. A remote authenticated user with an expired password using an alternative authentication method, such as SSH public key authentication, can exploit this flaw to bypass access control restrictions and gain unauthorized access to protected systems.
CVE-2026-104043 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-06 5.5 Medium
A flaw was found in SSSD. A local attacker with access to the Name Service Switch (NSS) responder UNIX socket can trigger an integer underflow by sending a specially crafted request with an undersized packet header. This issue causes an out-of-bounds memory read during packet parsing, crashing the responder process and resulting in a Denial of Service (DoS).
CVE-2026-4948 2 Firewalld, Redhat 7 Firewalld, Enterprise Linux, Enterprise Linux Eus and 4 more 2026-10-06 5.5 Medium
A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations.
CVE-2026-19617 1 Redhat 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more 2026-10-02 5.5 Medium
A flaw was found in libdm. A local attacker could craft a malicious Logical Volume Manager (LVM) metadata configuration with deeply nested structures. This could lead to uncontrolled recursion in the libdm configuration file parser, exhausting the stack and causing any LVM command reading the metadata to crash. This vulnerability results in a Denial of Service (DoS) for affected systems.
CVE-2026-75886 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-01 7.2 High
A flaw was found in openshift/console. An unauthenticated remote attacker can exploit a misconfiguration in the CatalogdHandler, which lacks proper authentication, and the forwarding of the `openshift-session-token` cookie. This allows the attacker to send requests to the in-cluster catalogd service, leading to the disclosure of the internal operator-catalog index and providing a relay into the openshift-catalogd namespace.
CVE-2026-1784 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-01 8.8 High
The Route OpenShift resource allows to define routes to make pods reachable at a subdomain through HAProxy. It was found that the checks performed on the spec.path YAML stanza in a Route document was insufficient and could allow a controlled injection of the HAProxy configuration.
CVE-2026-66792 1 Redhat 6 Acm, Advanced Cluster Management For Kubernetes, Multicluster Globalhub and 3 more 2026-09-29 9.9 Critical
A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a user on a managed cluster to escalate their privileges by creating a Subscription with specific, crafted annotations. Successful exploitation grants the attacker the ability to deploy resources into any namespace with the elevated permissions of the controller's Service Account, potentially leading to unauthorized access and control over cluster resources.
CVE-2026-10805 1 Redhat 14 Enterprise Linux, Hummingbird, Jboss Enterprise Application Platform Expansion Pack and 11 more 2026-09-25 6.7 Medium
A flaw was found in NetworkManager. This local privilege escalation vulnerability exists in NetworkManager's dhclient backend when processing malformed Manufacturer Usage Description (MUD) URLs. A local user can exploit this flaw to escalate privileges by triggering a script via a crafted MUD URL, provided an administrator has explicitly configured NetworkManager to use dhclient. This issue does not affect default configurations of NetworkManager.
CVE-2023-6563 1 Redhat 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more 2026-09-22 7.7 High
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
CVE-2026-6862 2 Redhat, Ubuntu 5 Enterprise Linux, Hummingbird, Openshift and 2 more 2026-09-21 5.5 Medium
A flaw was found in libefiboot, a component of efivar. The device path node parser in libefiboot fails to validate that each node's Length field is at least 4 bytes, which is the minimum size for an EFI (Extensible Firmware Interface) device path node header. A local user could exploit this vulnerability by providing a specially crafted device path node. This can lead to infinite recursion, causing stack exhaustion and a process crash, resulting in a denial of service (DoS).
