CVE-2025-14523 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-03-19 8.2 High
A flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.
CVE-2025-12105 1 Redhat 2 Enterprise Linux, Enterprise Linux Eus 2026-03-19 7.5 High
A flaw was found in the asynchronous message queue handling of the libsoup library, widely used by GNOME and WebKit-based applications to manage HTTP/2 communications. When network operations are aborted at specific timing intervals, an internal message queue item may be freed twice due to missing state synchronization. This leads to a use-after-free memory access, potentially crashing the affected application. Attackers could exploit this behavior remotely by triggering specific HTTP/2 read and cancel sequences, resulting in a denial-of-service condition.
CVE-2025-11021 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-03-19 7.5 High
A flaw was found in the cookie date handling logic of the libsoup HTTP library, widely used by GNOME and other applications for web communication. When processing cookies with specially crafted expiration dates, the library may perform an out-of-bounds memory read. This flaw could result in unintended disclosure of memory contents, potentially exposing sensitive information from the process using libsoup.
CVE-2026-1489 1 Redhat 1 Enterprise Linux 2026-03-19 5.4 Medium
A flaw was found in GLib. An integer overflow vulnerability in its Unicode case conversion implementation can lead to memory corruption. By processing specially crafted and extremely large Unicode strings, an attacker could trigger an undersized memory allocation, resulting in out-of-bounds writes. This could cause applications utilizing GLib for string conversion to crash or become unstable.
CVE-2026-1484 1 Redhat 1 Enterprise Linux 2026-03-19 4.2 Medium
A flaw was found in the GLib Base64 encoding routine when processing very large input data. Due to incorrect use of integer types during length calculation, the library may miscalculate buffer boundaries. This can cause memory writes outside the allocated buffer. Applications that process untrusted or extremely large Base64 input using GLib may crash or behave unpredictably.
CVE-2026-0988 1 Redhat 1 Enterprise Linux 2026-03-19 3.7 Low
A flaw was found in glib. Missing validation of offset and count parameters in the g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When specially crafted values are provided, this overflow results in an incorrect size being passed to memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service (DoS).
CVE-2025-14512 2 Gnome, Redhat 3 Glib, Enterprise Linux, Openshift 2026-03-19 6.5 Medium
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.
CVE-2025-13601 2 Gnome, Redhat 40 Glib, Ceph Storage, Codeready Linux Builder and 37 more 2026-03-19 7.7 High
A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.
CVE-2025-0620 2 Redhat, Samba 3 Enterprise Linux, Openshift, Samba 2026-03-18 4.9 Medium
A flaw was found in Samba. The smbd service daemon does not pick up group membership changes when re-authenticating an expired SMB session. This issue can expose file shares until clients disconnect and then connect again.
CVE-2025-5318 2 Libssh, Redhat 11 Libssh, Ai Inference Server, Enterprise Linux and 8 more 2026-03-18 8.1 High
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-2026-1485 1 Redhat 1 Enterprise Linux 2026-03-18 2.8 Low
A flaw was found in Glib's content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability.
CVE-2025-14104 1 Redhat 5 Ceph Storage, Enterprise Linux, Insights Proxy and 2 more 2026-03-18 6.1 Medium
A flaw was found in util-linux. This vulnerability allows a heap buffer overread when processing 256-byte usernames, specifically within the `setpwnam()` function, affecting SUID (Set User ID) login-utils utilities writing to the password database.
CVE-2025-14087 2 Gnome, Redhat 2 Glib, Enterprise Linux 2026-03-18 5.6 Medium
A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings.
CVE-2025-2241 1 Redhat 2 Acm, Multicluster Engine 2026-03-18 8.2 High
A flaw was found in Hive, a component of Multicluster Engine (MCE) and Advanced Cluster Management (ACM). This vulnerability causes VCenter credentials to be exposed in the ClusterProvision object after provisioning a VSphere cluster. Users with read access to ClusterProvision objects can extract sensitive credentials even if they do not have direct access to Kubernetes Secrets. This issue can lead to unauthorized VCenter access, cluster management, and privilege escalation.
CVE-2025-13033 1 Redhat 3 Acm, Ceph Storage, Rhdh 2026-03-18 7.5 High
A vulnerability was identified in the email parsing library due to improper handling of specially formatted recipient email addresses. An attacker can exploit this flaw by crafting a recipient address that embeds an external address within quotes. This causes the application to misdirect the email to the attacker's external address instead of the intended internal recipient. This could lead to a significant data leak of sensitive information and allow an attacker to bypass security filters and access controls.
CVE-2024-9632 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-03-18 7.8 High
A flaw was found in the X.org server. Due to improperly tracked allocation size in _XkbSetCompatMap, a local attacker may be able to trigger a buffer overflow condition via a specially crafted payload, leading to denial of service or local privilege escalation in distributions where the X.org server is run with root privileges.
CVE-2023-5157 3 Fedoraproject, Mariadb, Redhat 17 Fedora, Mariadb, Enterprise Linux and 14 more 2026-03-18 7.5 High
A vulnerability was found in MariaDB. An OpenVAS port scan on ports 3306 and 4567 allows a malicious remote client to cause a denial of service.
CVE-2026-2603 2 Keycloak, Redhat 2 Keycloak, Build Keycloak 2026-03-18 8.1 High
A flaw was found in Keycloak. A remote attacker could bypass security controls by sending a valid SAML response from an external Identity Provider (IdP) to the Keycloak SAML endpoint for IdP-initiated broker logins. This allows the attacker to complete broker logins even when the SAML Identity Provider is disabled, leading to unauthorized authentication.
CVE-2026-2092 1 Redhat 1 Build Keycloak 2026-03-18 7.7 High
A flaw was found in Keycloak. Keycloak's Security Assertion Markup Language (SAML) broker endpoint does not properly validate encrypted assertions when the overall SAML response is not signed. An attacker with a valid signed SAML assertion can exploit this by crafting a malicious SAML response. This allows the attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure.
CVE-2026-2575 2 Keycloak, Redhat 2 Keycloak, Build Keycloak 2026-03-18 5.3 Medium
A flaw was found in Keycloak. An unauthenticated remote attacker can trigger an application level Denial of Service (DoS) by sending a highly compressed SAMLRequest through the SAML Redirect Binding. The server fails to enforce size limits during DEFLATE decompression, leading to an OutOfMemoryError (OOM) and subsequent process termination. This vulnerability allows an attacker to disrupt the availability of the service.
