CVE-2026-42784 3 Red Hat, Redhat, Sequoia-pgp 12 Enterprise Linux, Ansible Automation Platform, Confidential Compute Attestation and 9 more 2026-10-07 7.4 High
A flaw was found in sequoia-openpgp. The library incorrectly infers key flags for older certificates when a key flags subpacket is missing, leading to a discrepancy in how key capabilities are viewed. This key flag confusion allows an attacker to bypass the back-signature check. Consequently, an attacker can illegitimately bind an arbitrary subkey to their own certificate and forge signatures, completely compromising cryptographic integrity.
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-2026-49329 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-07 7.5 High
A flaw was found in openshift/oauth-server. The OAuth login and error page endpoints pass the unauthenticated Accept-Language header to golang.org/x/text/language.ParseAcceptLanguage() without input validation. A bypass of the CVE-2022-32149 mitigation exists: the upstream guard counts only '-' characters but the internal BCP 47 scanner aliases '_' to '-' after the guard check. An unauthenticated attacker can send a crafted Accept-Language header using '_' separators to trigger quadratic-time parsing, consuming excessive CPU and denying authentication to all cluster users.
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-2026-55655 3 Openbsd, Openssh, Redhat 10 Openssh, Openssh, Enterprise Linux and 7 more 2026-10-07 5 Medium
A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack can compromise the confidentiality of forwarded X11 traffic, including sensitive window contents and input, and may allow some manipulation of the forwarded session.
CVE-2026-55653 3 Openbsd, Openssh, Redhat 10 Openssh, Openssh, Enterprise Linux and 7 more 2026-10-07 4.3 Medium
A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS).
CVE-2026-104030 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. This vulnerability allows a local user to cause a Denial of Service (DoS) by submitting a specially crafted passkey authentication token that lacks null terminators. The authentication service reads past the end of the provided memory buffer, causing the process to crash and disrupting authentication services.
CVE-2026-104029 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-06 3.3 Low
A flaw was found in SSSD. A local attacker can exploit this vulnerability by sending a specially crafted request to the autofs responder UNIX socket. Due to improper buffer offset calculation during request parsing, the service performs an out-of-bounds memory read. This flaw can cause the autofs responder process to crash, resulting in a denial of service (DoS).
CVE-2026-104032 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. An unprivileged local user can repeatedly request master automount map updates through the autofs responder due to missing authorization checks. This triggers global cache invalidation and forces repeated lookups to backend directory providers, leading to a Denial of Service (DoS) from degraded automount availability and elevated resource consumption.
CVE-2026-104033 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-06 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-2026-104034 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-2026-104035 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. 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-2026-104036 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-2026-104037 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 can exploit this issue by sending a specially crafted request with an invalid packet length to the autofs responder UNIX socket. This causes an integer underflow and an out-of-bounds memory read, which can crash the responder process and result in a denial of service (DoS).
CVE-2026-104038 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-06 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-2026-104039 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 local user can cause a denial of service (DoS) by disrupting system authentication services. When handling Generic Security Services Application Programming Interface (GSSAPI) authentication in the Pluggable Authentication Module (PAM) responder, cached connection state is freed upon completion without clearing the reference pointer. An attacker can exploit this by sending an additional request over the same connection, causing the service to access invalid memory and unexpectedly terminate.
CVE-2026-104040 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-06 4.4 Medium
A flaw was found in SSSD. When configured with the Entra ID identity provider, input lookup names containing single quotes are not properly escaped before being included in Microsoft Graph Open Data Protocol (OData) queries. A low-privileged local user can exploit this flaw by submitting a crafted search request, altering query filters to broaden user or group searches. This can lead to information disclosure by retrieving unintended directory objects, as well as a Denial of Service (DoS) through excessive processing and cache population.
CVE-2026-104042 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 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.
