The MCS endpoint (port 22623) provides ignition configuration used for bootstrapping Nodes and can include some sensitive data, e.g. registry pull secrets. There are two scenarios whe

CVE-2026-6845 [MEDIUM] CWE-476 CVE-2026-6845: A flaw was found in binutils, specifically within the `readelf` utility. This vulnerability allows a A flaw was found in binutils, specifically within the `readelf` utility. This vulnerability allows a local attacker to cause a Denial of Service (DoS) by tricking a user into processing a specially crafted Executable and Linkable Format (ELF) file. The exploitation of this flaw can lead to the system becoming unresponsive due to excessive resource con

CVE-2019-1003010 [MEDIUM] CWE-352 CVE-2019-1003010: A cross-site request forgery vulnerability exists in Jenkins Git Plugin 3.9.1 and earlier in src/mai A cross-site request forgery vulnerability exists in Jenkins Git Plugin 3.9.1 and earlier in src/main/java/hudson/plugins/git/GitTagAction.java that allows attackers to create a Git tag in a workspace and attach corresponding metadata to a build record.

CVE-2026-104045 [MEDIUM] CWE-772 CVE-2026-104045: A flaw was found in SSSD. A local user can trigger a Denial of Service (DoS) by exploiting a race co 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 consumpti

CVE-2026-13002 [MEDIUM] CWE-835 CVE-2026-13002: A flow has been identified into dnssec.c library, causing an infinite loop to dnsmasq service. An at A flow has been identified into dnssec.c library, causing an infinite loop to dnsmasq service. An attacker who controls any DNSSEC-signed zone can hang the dnsmasq process with a single crafted response, killing all DNS resolution for its clients.

CVE-2026-0989 [LOW] CWE-674 CVE-2026-0989: A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating

CVE-2020-25639 [MEDIUM] CWE-476 CVE-2020-25639: A NULL pointer dereference flaw was found in the Linux kernel's GPU Nouveau driver functionality in A NULL pointer dereference flaw was found in the Linux kernel's GPU Nouveau driver functionality in versions prior to 5.12-rc1 in the way the user calls ioctl DRM_IOCTL_NOUVEAU_CHANNEL_ALLOC. This flaw allows a local user to crash the system.

CVE-2016-8651 [LOW] CWE-20 CVE-2016-8651: An input validation flaw was found in the way OpenShift 3 handles requests for images. A user, with An input validation flaw was found in the way OpenShift 3 handles requests for images. A user, with a copy of the manifest associated with an image, can pull an image even if they do not have access to the image normally, resulting in the disclosure of any information contained within the image.

CVE-2025-8283 [LOW] CWE-15 CVE-2025-8283: A vulnerability was found in the netavark package, a network stack for containers used with Podman. A vulnerability was found in the netavark package, a network stack for containers used with Podman. Due to dns.podman search domain being removed, netavark may return external servers if a valid A/AAAA record is sent as a response. When creating a container with a given name, this name will be used as the hostname for the container itself, as the podman's

CVE-2026-0992 [LOW] CWE-400 CVE-2026-0992: A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU c

CVE-2026-68744 [LOW] CWE-908 CVE-2026-68744: A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-alloc A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client. A local attacker can exploit this to disclose cached directory data and heap layout informati

CVE-2025-6170 [LOW] CWE-121 CVE-2025-6170: A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML fil A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.

CVE-2019-3815 [LOW] CVE-2019-3815: A memory leak was discovered in the backport of fixes for CVE-2018-16864 in Red Hat Enterprise Linux A memory leak was discovered in the backport of fixes for CVE-2018-16864 in Red Hat Enterprise Linux. Function dispatch_message_real() in journald-server.c does not free the memory allocated by set_iovec_field_free() to store the `_CMDLINE=` entry. A local attacker may use this flaw to make systemd-journald crash. This issue only affects versions shipped with Re

CVE-2019-10165 [LOW] CWE-532 CVE-2019-10165: OpenShift Container Platform before version 4.1.3 writes OAuth tokens in plaintext to the audit logs OpenShift Container Platform before version 4.1.3 writes OAuth tokens in plaintext to the audit logs for the Kubernetes API server and OpenShift API server. A user with sufficient privileges could recover OAuth tokens from these audit logs and use them to access other resources.
