High [CVE-2025-11393] Insights-runtimes-tech-preview/runtimes-inventory-rhel8-operator: improper proxy configuration allows unauthorized administrative commands
A flaw was found in runtimes-inventory-rhel8-operator. An internal proxy component is incorrectly configured. Because of this flaw, the proxy attaches the cluster's main administrative credentials to any command it receives, instead of only the specific reports it is supposed to handle. This allows a standard user within the cluster to send unauthorized commands to the management platform, effectively acting with the full permissions of the cluster administrator. This could lead to unauthorized changes to the cluster's configuration or status on the Red Hat platform. Affected products named by the advisory: Red Hat Lightspeed (formerly Insights) for Runtimes 1.0; Red Hat Runtimes Inventory Operator.
Medium [CVE-2025-14512] integer overflow in glib gio attribute escaping causes heap buffer overflow
A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing malicious file or remote filesystem attribute values. This vulnerability is rated Moderate for Red Hat products because an integer overflow in GLib's GIO `escape_byte_string()` function can lead to a heap buffer overflow and denial-of-service. This occurs when processing specially crafted file or remote filesystem attribute values, requiring an attacker to provide malicious input. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-190.

High [CVE-2025-9784] Undertow: undertow madeyoureset http/2 ddos vulnerability
A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS). Affected products named by the advisory: Red Hat JBoss Enterprise Application Platform; Red Hat JBoss Enterprise Application Platform 7.1 EUS for RHEL 7; Red Hat JBoss Enterprise Application Platform 7.3 EUS for RHEL 7; Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7; and 12 more.

Medium [CVE-2025-7195] Operator-sdk: privilege escalation due to incorrect permissions of /etc/passwd
Early versions of Operator-SDK provided an insecure method to allow operator containers to run in environments that used a random UID. Operator-SDK before 0.15.2 provided a script, user_setup, which modifies the permissions of the /etc/passwd file to 664 during build time. Developers who used Operator-SDK before 0.15.2 to scaffold their operator may still be impacted by this if the insecure user_setup script is still being used to build new container images. In affected images, the /etc/passwd file is created during build time with group-writable permissions and a group ownership of root (gid=0). An attacker who can execute commands within an affected container, even as a non-root user, may be able to leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container. Affected products named by the advisory: RHEL-9-CNV-4.17; RHEL-9-CNV-4.18; RHEL-9-CNV-4.20; Compliance Operator 1; and 12 more. Affected products named by the advisory: Red Hat Advanced Cluster Management for Kubernetes 2.11; Red Hat Advanced Cluster Management for Kubernetes 2.12; Red Hat Advanced Cluster Management for Kubernetes 2.13; Red Hat Advanced Cluster Management for Kubernetes 2.14; and 8 more.
High [CVE-2025-7425] Libxslt: libxml2: heap use-after-free in libxslt caused by atype corruption in xmlattrptr
A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7 Extended Lifecycle Support; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 8.2 Advanced Update Support; and 29 more. Affected products named by the advisory: Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support; Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On; Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support; Red Hat Enterprise Linux 8.6 Telecommunications Update Service; and 27 more.

Affected products named by the advisory: Red Hat Enterprise Linux 9.4 Extended Update Support; Red Hat Ceph Storage 7; Red Hat Discovery 2; Red Hat Insights proxy 1.5; and 1 more.
Medium [CVE-2025-32989] Gnutls: vulnerability in gnutls sct extension parsing
A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions; Red Hat Enterprise Linux 9.4 Extended Update Support; and 5 more. Affected products named by the advisory: Red Hat Ceph Storage 7; Red Hat Discovery 2; Red Hat Hardened Images; Red Hat Insights proxy 1.5; and 1 more. Affected products named by the advisory: Red Hat OpenShift Container Platform 4.
Medium [CVE-2025-32988] Gnutls: vulnerability in gnutls othername san export
A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions; and 6 more. Affected products named by the advisory: Red Hat Enterprise Linux 9.4 Extended Update Support; Red Hat Ceph Storage 7; Red Hat Discovery 2; Red Hat Hardened Images; and 2 more.
