CVE-2025-62231 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-20 7.3 High
A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
CVE-2025-59089 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-04-20 5.9 Medium
If an attacker causes kdcproxy to connect to an attacker-controlled KDC server (e.g. through server-side request forgery), they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copies the entire buffered stream into a new buffer on each recv() call, even when the transfer is incomplete, causing excessive memory allocation and CPU usage. Additionally, kdcproxy accepts incoming response chunks as long as the received data length is not exactly equal to the length indicated in the response header, even when individual chunks or the total buffer exceed the maximum length of a Kerberos message. This allows an attacker to send unbounded data until the connection timeout is reached (approximately 12 seconds), exhausting server memory or CPU resources. Multiple concurrent requests can cause accept queue overflow, denying service to legitimate clients.
CVE-2026-0719 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift Devspaces and 6 more 2026-04-18 8.6 High
A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in incorrect memory allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may crash unexpectedly, creating a denial-of-service risk.
CVE-2026-1761 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift Devspaces and 6 more 2026-04-16 8.6 High
A flaw was found in libsoup. This stack-based buffer overflow vulnerability occurs during the parsing of multipart HTTP responses due to an incorrect length calculation. A remote attacker can exploit this by sending a specially crafted multipart HTTP response, which can lead to memory corruption. This issue may result in application crashes or arbitrary code execution in applications that process untrusted server responses, and it does not require authentication or user interaction.
CVE-2025-5024 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-04-15 7.4 High
A flaw was found in gnome-remote-desktop. Once gnome-remote-desktop listens for RDP connections, an unauthenticated attacker can exhaust system resources and repeatedly crash the process. There may be a resource leak after many attacks, which will also result in gnome-remote-desktop no longer being able to open files even after it is restarted via systemd.
CVE-2025-49180 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 7.8 High
A flaw was found in the RandR extension, where the RRChangeProviderProperty function does not properly validate input. This issue leads to an integer overflow when computing the total size to allocate.
CVE-2025-11561 1 Redhat 9 Ceph Storage, Enterprise Linux, Openshift and 6 more 2026-04-15 8.8 High
A flaw was found in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. In default configurations, the Kerberos local authentication plugin (sssd_krb5_localauth_plugin) is enabled, but a fallback to the an2ln plugin is possible. This fallback allows an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users, potentially resulting in unauthorized access or privilege escalation on domain-joined Linux hosts.
CVE-2025-14242 1 Redhat 7 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 4 more 2026-04-15 6.5 Medium
A flaw was found in vsftpd. This vulnerability allows a denial of service (DoS) via an integer overflow in the ls command parameter parsing, triggered by a remote, authenticated attacker sending a crafted STAT command with a specific byte sequence.
CVE-2025-14523 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-04-15 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-2025-14905 1 Redhat 12 Directory Server, Directory Server E4s, Directory Server Eus and 9 more 2026-04-15 7.2 High
A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE).
CVE-2025-49175 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 6.1 Medium
A flaw was found in the X Rendering extension's handling of animated cursors. If a client provides no cursors, the server assumes at least one is present, leading to an out-of-bounds read and potential crash.
CVE-2025-49176 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 7.3 High
A flaw was found in the Big Requests extension. The request length is multiplied by 4 before checking against the maximum allowed size, potentially causing an integer overflow and bypassing the size check.
CVE-2025-3576 1 Redhat 8 Discovery, Enterprise Linux, Openshift and 5 more 2026-04-15 5.9 Medium
A vulnerability in the MIT Kerberos implementation allows GSSAPI-protected messages using RC4-HMAC-MD5 to be spoofed due to weaknesses in the MD5 checksum design. If RC4 is preferred over stronger encryption types, an attacker could exploit MD5 collisions to forge message integrity codes. This may lead to unauthorized message tampering.
CVE-2025-49178 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 5.5 Medium
A flaw was found in the X server's request handling. Non-zero 'bytes to ignore' in a client's request can cause the server to skip processing another client's request, potentially leading to a denial of service.
CVE-2025-8067 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 8.5 High
A flaw was found in the Udisks daemon, where it allows unprivileged users to create loop devices using the D-BUS system. This is achieved via the loop device handler, which handles requests sent through the D-BUS interface. As two of the parameters of this handle, it receives the file descriptor list and index specifying the file where the loop device should be backed. The function itself validates the index value to ensure it isn't bigger than the maximum value allowed. However, it fails to validate the lower bound, allowing the index parameter to be a negative value. Under these circumstances, an attacker can cause the UDisks daemon to crash or perform a local privilege escalation by gaining access to files owned by privileged users.
CVE-2025-59088 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-04-15 8.6 High
If kdcproxy receives a request for a realm which does not have server addresses defined in its configuration, by default, it will query SRV records in the DNS zone matching the requested realm name. This creates a server-side request forgery vulnerability, since an attacker could send a request for a realm matching a DNS zone where they created SRV records pointing to arbitrary ports and hostnames (which may resolve to loopback or internal IP addresses). This vulnerability can be exploited to probe internal network topology and firewall rules, perform port scanning, and exfiltrate data. Deployments where the "use_dns" setting is explicitly set to false are not affected.
CVE-2025-66287 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 8.8 High
A flaw was found in WebKitGTK. Processing malicious web content can cause an unexpected process crash due to improper memory handling.
CVE-2025-7493 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 9.1 Critical
A privilege escalation flaw from host to domain administrator was found in FreeIPA. This vulnerability is similar to CVE-2025-4404, where it fails to validate the uniqueness of the krbCanonicalName. While the previously released version added validations for the admin@REALM credential, FreeIPA still does not validate the root@REALM canonical name, which can also be used as the realm administrator's name. This flaw allows an attacker to perform administrative tasks over the REALM, leading to access to sensitive data and sensitive data exfiltration.
