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-2026-104032 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-2026-104034 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-2026-104031 3 Red Hat, Redhat, Sssd 5 Enterprise Linux, Enterprise Linux, Openshift and 2 more 2026-10-06 5.5 Medium
A flaw was found in SSSD. In configurations where the autofs responder service is enabled, memory allocated during successful request processing is not released until the client connection terminates. A local attacker can exploit this vulnerability by maintaining an open connection and repeatedly submitting valid requests, leading to memory exhaustion and a Denial of Service (DoS).
CVE-2026-104041 2 Redhat, Sssd 3 Enterprise Linux, Openshift, Sssd 2026-10-06 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-2026-79705 1 Redhat 7 Ansible Automation Platform, Container Native Virtualization, Enterprise Linux and 4 more 2026-10-02 4.5 Medium
A flaw was found in the buildah/copier Go package. When used outside of Buildah by a non-root caller, a crafted tar archive containing malicious symlinks can escape the target extraction directory and create files outside the intended destination. Buildah itself uses chroot hardening and is not affected.
CVE-2026-88265 1 Redhat 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more 2026-10-02 5.6 Medium
A flaw was found in crun. After pivot_root, reopening /dev/null for stdio can follow a symlink and attach a host file to container stdio, then change that file's ownership. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh /dev are not exposed. No fixed release is available yet.
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-2026-102010 2 Gnu, Redhat 6 Gcc, Enterprise Linux, Hardened Images and 3 more 2026-10-02 7 High
A flaw was found in GCC. When an application calls the erase_if function on a binary heap priority queue in libstdc++, the library reallocates storage but fails to update its internal entry pointer. An attacker capable of triggering this operation can exploit this use-after-free condition, leading to a Denial of Service (DoS) via an application crash or potential memory corruption.
CVE-2026-16529 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift and 6 more 2026-10-01 7.5 High
A signed integer overflow in the PCP __pmGetPDU() function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service (DoS) for subsequent packet reads.
CVE-2026-16527 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift and 6 more 2026-10-01 7.3 High
An unauthenticated remote attacker can bypass access controls by sending crafted requests to the PCP pmproxy /store endpoint. This allows the attacker to overwrite any PMDA metric, leading to arbitrary code execution and system takeover.
CVE-2026-16526 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift and 6 more 2026-10-01 8.8 High
A flaw in the PCP linux_sockets module exposes an unsecured internal connection. An attacker with initial code execution can exploit this to escalate privileges and execute arbitrary commands as root.
CVE-2026-16524 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift and 6 more 2026-10-01 7.8 High
A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric. This failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh.
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-2026-15809 1 Redhat 4 Confidential Compute Attestation, Openshift, Openshift Container Platform and 1 more 2026-10-01 7.8 High
A flaw was found in CRI-O. The fix for a previous vulnerability (CVE-2022-4318) was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitrary lines into /etc/passwd by use of a specially crafted environment variable.
CVE-2026-86330 1 Redhat 1 Openshift Data Foundation 2026-09-30 7.2 High
An OS command injection flaw was found in the set_hostname_internal function of NooBaa's cluster_internal_api. This component is responsible for managing the Multi-Cloud Object Gateway in OpenShift Data Foundation. The vulnerability occurs because the hostname parameter is passed directly to a shell command without proper sanitization. An authenticated attacker with administrative privileges can provide a specially crafted hostname containing shell metacharacters to execute arbitrary commands on the host system with the privileges of the NooBaa process.
CVE-2026-101295 1 Redhat 2 Assisted Installer, Openshift 2026-09-30 7.3 High
Path traversal / arbitrary file write in oc-mirror's operator catalog image extraction. When mirroring operator catalogs using either the legacy v1 path (--v1) or the OCI feature path (--use-oci-feature), oc-mirror extracts tar entries from catalog image layers without validating that file paths resolve within the intended destination directory.
