| A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon logs LUKS disk encryption passphrases in plaintext to a log file. The log file is created without restrictive permissions, making it world-readable under the default process umask. A local attacker can read the log file to obtain the LUKS passphrase. | ||||
| CVE-2025-5318 | 2 Libssh, Redhat | 11 Libssh, Ai Inference Server, Enterprise Linux and 8 more | 2026-11-05 | 5.4 Medium |
| A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior. | ||||
| CVE-2026-0966 | 2 Libssh, Redhat | 7 Libssh, Enterprise Linux, Hardened Images and 4 more | 2026-11-05 | 8.2 High |
| A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the server's logging verbosity is set to `SSH_LOG_PACKET (3)` or higher. Successful exploitation could lead to a self-Denial of Service of the per-connection daemon process. | ||||

| A flaw was found in luksmeta. A local attacker with administrative privileges can cause data corruption when saving metadata to a Linux Unified Key Setup (LUKS) device. Due to incorrect boundary calculations and flawed overlap detection, new metadata entries can be written beyond available free space or over existing records. This issue can corrupt stored encrypted payload data or existing metadata, potentially rendering the affected data inaccessible. | ||||
| CVE-2026-104048 | 3 Fedoraproject, Redhat, Sssd | 6 Sssd, Enterprise Linux, Openshift and 3 more | 2026-11-05 | 6.8 Medium |
| A flaw was found in SSSD. In trust-enabled identity management environments, SSSD evaluates Host-Based Access Control (HBAC) rules by stripping domain qualifiers and comparing only short usernames. An authenticated user in a trusted domain who shares the same username as an authorized local account can bypass access policies and gain unauthorized access to protected services or hosts. | ||||
| CVE-2026-104047 | 3 Fedoraproject, Redhat, Sssd | 6 Sssd, Enterprise Linux, Openshift and 3 more | 2026-11-05 | 5.3 Medium |
| A flaw was found in SSSD. When configured to use Microsoft Entra ID, search inputs are not properly sanitized before being incorporated into directory query filters. A local user can exploit this vulnerability by submitting a crafted lookup request, manipulating the query logic to cause unauthorized information disclosure from the directory. | ||||
| CVE-2026-104046 | 3 Fedoraproject, Redhat, Sssd | 6 Sssd, Enterprise Linux, Openshift and 3 more | 2026-11-05 | 6.2 Medium |
| A flaw was found in SSSD (System Security Services Daemon). When Identity Provider (IdP) authentication is enabled, pre-authentication requests retain state in memory without being cleared or timed out. A local attacker can repeatedly initiate authentication flows without completing them, causing unbounded memory consumption. This memory exhaustion can lead to a Denial of Service (DoS) by degrading or terminating SSSD authentication services. | ||||
| CVE-2026-104045 | 3 Fedoraproject, Redhat, Sssd | 6 Sssd, Enterprise Linux, Openshift and 3 more | 2026-11-05 | 4.7 Medium |
| A flaw was found in SSSD. A local user can trigger a Denial of Service (DoS) by exploiting a race condition in the autofs responder between asynchronous enumeration completion and map invalidation. By repeatedly sending concurrent map enumeration and invalidation requests, an attacker can cause memory to leak, leading to excessive memory consumption that can disrupt or crash the autofs service. | ||||
| CVE-2026-104044 | 2 Redhat, Sssd | 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more | 2026-11-05 | 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-2026-104043 | 2 Redhat, Sssd | 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more | 2026-11-05 | 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-2026-104042 | 2 Redhat, Sssd | 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more | 2026-11-05 | 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-2026-104041 | 2 Redhat, Sssd | 4 Enterprise Linux, Openshift, Rhel Els and 1 more | 2026-11-05 | 5.5 Medium |
| A flaw was found in SSSD. An unprivileged local user can repeatedly request lookups for nonexistent entries through the Name Service Switch (NSS) responder. Because the negative cache does not limit the total number of stored entries and only removes expired records when an existing key is rechecked, the cache can grow without bound. This behavior can lead to memory exhaustion, resulting in a Denial of Service (DoS) as the responder becomes unresponsive or terminates. | ||||
| CVE-2026-104039 | 3 Fedoraproject, Redhat, Sssd | 6 Sssd, Enterprise Linux, Openshift and 3 more | 2026-11-05 | 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-2026-104038 | 2 Redhat, Sssd | 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more | 2026-11-05 | 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-2026-104037 | 2 Redhat, Sssd | 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more | 2026-11-05 | 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-2026-104036 | 2 Redhat, Sssd | 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more | 2026-11-05 | 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-2026-104035 | 2 Redhat, Sssd | 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more | 2026-11-05 | 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. | ||||
