CVE-2026-35091 2 Corosync, Redhat 4 Corosync, Enterprise Linux, Openshift and 1 more 2026-04-08 8.2 High
A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol (UDP) packet. This can lead to an out-of-bounds read, causing a denial of service (DoS) and potentially disclosing limited memory contents. This vulnerability affects Corosync when running in totemudp/totemudpu mode, which is the default configuration.
CVE-2026-35092 2 Corosync, Redhat 4 Corosync, Enterprise Linux, Openshift and 1 more 2026-04-08 7.5 High
A flaw was found in Corosync. An integer overflow vulnerability in Corosync's join message sanity validation allows a remote, unauthenticated attacker to send crafted User Datagram Protocol (UDP) packets. This can cause the service to crash, leading to a denial of service. This vulnerability specifically affects Corosync deployments configured to use totemudp/totemudpu mode.
CVE-2026-35093 3 Fedoraproject, Freedesktop, Redhat 3 Fedora, Libinput, Enterprise Linux 2026-04-08 8.8 High
A flaw was found in libinput. A local attacker who can place a specially crafted Lua bytecode file in certain system or user configuration directories can bypass security restrictions. This allows the attacker to run unauthorized code with the same permissions as the program using libinput, such as a graphical compositor. This could lead to the attacker monitoring keyboard input and sending that information to an external location.
CVE-2026-35094 3 Fedoraproject, Freedesktop, Redhat 3 Fedora, Libinput, Enterprise Linux 2026-04-08 3.3 Low
A flaw was found in libinput. An attacker capable of deploying a Lua plugin file in specific system directories can exploit a dangling pointer vulnerability. This occurs when a garbage collection cleanup function is called, leaving a pointer that can then be printed to system logs. This could potentially expose sensitive data if the memory location is re-used, leading to information disclosure. For this exploit to work, Lua plugins must be enabled in libinput and loaded by the compositor.
CVE-2022-45063 3 Fedoraproject, Invisible-island, Redhat 3 Fedora, Xterm, Enterprise Linux 2026-04-08 9.8 Critical
xterm before 375 allows code execution via font ops, e.g., because an OSC 50 response may have Ctrl-g and therefore lead to command execution within the vi line-editing mode of Zsh. NOTE: font ops are not allowed in the xterm default configurations of some Linux distributions.
CVE-2026-2625 2 Redhat, Rust-rpm-sequoia 3 Enterprise Linux, Hummingbird, Rust-rpm-sequoia 2026-04-08 4 Medium
A flaw was found in rust-rpm-sequoia. An attacker can exploit this vulnerability by providing a specially crafted Red Hat Package Manager (RPM) file. During the RPM signature verification process, this crafted file can trigger an error in the OpenPGP signature parsing code, leading to an unconditional termination of the rpm process. This issue results in an application level denial of service, making the system unable to process RPM files for signature verification.
CVE-2025-14104 1 Redhat 6 Ceph Storage, Enterprise Linux, Hummingbird and 3 more 2026-04-08 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-2026-1961 2 Red Hat, Redhat 5 Red Hat Satellite 6, Satellite, Satellite Capsule and 2 more 2026-04-08 8 High
A flaw was found in Foreman. A remote attacker could exploit a command injection vulnerability in Foreman's WebSocket proxy implementation. This vulnerability arises from the system's use of unsanitized hostname values from compute resource providers when constructing shell commands. By operating a malicious compute resource server, an attacker could achieve remote code execution on the Foreman server when a user accesses VM VNC console functionality. This could lead to the compromise of sensitive credentials and the entire managed infrastructure.
CVE-2026-28369 1 Redhat 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more 2026-04-08 8.7 High
A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted information, or manipulate web caches, potentially leading to unauthorized actions or data exposure.
CVE-2026-28368 1 Redhat 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more 2026-04-08 8.7 High
A flaw was found in Undertow. This vulnerability allows a remote attacker to construct specially crafted requests where header names are parsed differently by Undertow compared to upstream proxies. This discrepancy in header interpretation can be exploited to launch request smuggling attacks, potentially bypassing security controls and accessing unauthorized resources.
CVE-2026-5673 2 Redhat, Xiph 2 Enterprise Linux, Libtheora 2026-04-07 5.6 Medium
A flaw was found in libtheora. This heap-based out-of-bounds read vulnerability exists within the AVI (Audio Video Interleave) parser, specifically in the avi_parse_input_file() function. A local attacker could exploit this by tricking a user into opening a specially crafted AVI file containing a truncated header sub-chunk. This could lead to a denial-of-service (application crash) or potentially leak sensitive information from the heap.
CVE-2026-37977 1 Redhat 2 Build Keycloak, Build Of Keycloak 2026-04-07 3.7 Low
A flaw was found in Keycloak. A remote attacker can exploit a Cross-Origin Resource Sharing (CORS) header injection vulnerability in Keycloak's User-Managed Access (UMA) token endpoint. This flaw occurs because the `azp` claim from a client-supplied JSON Web Token (JWT) is used to set the `Access-Control-Allow-Origin` header before the JWT signature is validated. When a specially crafted JWT with an attacker-controlled `azp` value is processed, this value is reflected as the CORS origin, even if the grant is later rejected. This can lead to the exposure of low-sensitivity information from authorization server error responses, weakening origin isolation, but only when a target client is misconfigured with `webOrigins: ["*"]`.
CVE-2025-5372 2 Libssh, Redhat 5 Libssh, Enterprise Linux, Openshift and 2 more 2026-04-07 5 Medium
A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the ssh_kdf() function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success—the function may mistakenly return a success status even when key derivation fails. This results in uninitialized cryptographic key buffers being used in subsequent communication, potentially compromising SSH sessions' confidentiality, integrity, and availability.
CVE-2013-0270 2 Openstack, Redhat 2 Keystone, Openstack 2026-04-07 6.5 Medium
A flaw was found in OpenStack Keystone. A remote attacker could exploit this vulnerability by sending a large HTTP request, specifically by providing a long tenant name when requesting a token. This could lead to a denial of service, consuming excessive CPU and memory resources on the affected system.
CVE-2012-5571 2 Openstack, Redhat 3 Essex, Folsom, Openstack 2026-04-07 5.4 Medium
A flaw was found in OpenStack Keystone. This vulnerability allows remote authenticated users to bypass intended authorization restrictions. This occurs because OpenStack Keystone does not properly handle EC2 (Elastic Compute Cloud) tokens when a user's role has been removed from a tenant. An attacker can leverage a token associated with a removed user role to gain unauthorized access.
CVE-2023-3972 1 Redhat 23 Enterprise Linux, Enterprise Linux Aus, Enterprise Linux Desktop and 20 more 2026-04-06 7.8 High
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide).
CVE-2025-47268 2 Iputils, Redhat 2 Iputils, Enterprise Linux 2026-04-06 6.5 Medium
ping in iputils before 20250602 allows a denial of service (application error or incorrect data collection) via a crafted ICMP Echo Reply packet, because of a signed 64-bit integer overflow in timestamp multiplication.
CVE-2024-50120 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-04-06 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: smb: client: Handle kstrdup failures for passwords In smb3_reconfigure(), after duplicating ctx->password and ctx->password2 with kstrdup(), we need to check for allocation failures. If ses->password allocation fails, return -ENOMEM. If ses->password2 allocation fails, free ses->password, set it to NULL, and return -ENOMEM.
CVE-2025-21979 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-04-06 7.8 High
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: cancel wiphy_work before freeing wiphy A wiphy_work can be queued from the moment the wiphy is allocated and initialized (i.e. wiphy_new_nm). When a wiphy_work is queued, the rdev::wiphy_work is getting queued. If wiphy_free is called before the rdev::wiphy_work had a chance to run, the wiphy memory will be freed, and then when it eventally gets to run it'll use invalid memory. Fix this by canceling the work before freeing the wiphy.
CVE-2025-26601 3 Redhat, Tigervnc, X.org 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2026-04-06 7.8 High
A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger() is called. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers.
