| 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-2026-35091 | 2 Corosync, Redhat | 3 Corosync, Enterprise Linux, Openshift | 2026-04-07 | N/A | 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-2025-26601 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2026-04-06 | N/A | 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. | |||||
| CVE-2025-26600 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2026-04-06 | N/A | 7.8 HIGH |
| A use-after-free flaw was found in X.Org and Xwayland. When a device is removed while still frozen, the events queued for that device remain while the device is freed. Replaying the events will cause a use-after-free. | |||||
| CVE-2025-26599 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2026-04-06 | N/A | 7.8 HIGH |
| An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later. | |||||
| CVE-2025-26598 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2026-04-06 | N/A | 7.8 HIGH |
| An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access. | |||||
| CVE-2025-26597 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2026-04-06 | N/A | 7.8 HIGH |
| A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size. | |||||
| CVE-2025-26596 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2026-04-06 | N/A | 7.8 HIGH |
| A heap overflow flaw was found in X.Org and Xwayland. The computation of the length in XkbSizeKeySyms() differs from what is written in XkbWriteKeySyms(), which may lead to a heap-based buffer overflow. | |||||
| CVE-2025-26595 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2026-04-06 | N/A | 7.8 HIGH |
| A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size. | |||||
| CVE-2025-26594 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2026-04-06 | N/A | 7.8 HIGH |
| A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free. | |||||
| CVE-2026-2272 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-04-03 | N/A | 4.3 MEDIUM |
| A flaw was found in GIMP. An integer overflow vulnerability exists when processing ICO image files, specifically in the `ico_read_info` and `ico_read_icon` functions. This issue arises because a size calculation for image buffers can wrap around due to a 32-bit integer evaluation, allowing oversized image headers to bypass security checks. A remote attacker could exploit this by providing a specially crafted ICO file, leading to a buffer overflow and memory corruption, which may result in an application level denial of service. | |||||
| CVE-2026-2239 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-04-03 | N/A | 2.8 LOW |
| A flaw was found in GIMP. Heap-buffer-overflow vulnerability exists in the fread_pascal_string function when processing a specially crafted PSD (Photoshop Document) file. This occurs because the buffer allocated for a Pascal string is not properly null-terminated, leading to an out-of-bounds read when strlen() is subsequently called. Successfully exploiting this vulnerability can cause the application to crash, resulting in an application level Denial of Service. | |||||
| CVE-2026-0965 | 2 Libssh, Redhat | 2 Libssh, Enterprise Linux | 2026-04-02 | N/A | 3.3 LOW |
| A flaw was found in libssh where it can attempt to open arbitrary files during configuration parsing. A local attacker can exploit this by providing a malicious configuration file or when the system is misconfigured. This vulnerability could lead to a Denial of Service (DoS) by causing the system to try and access dangerous files, such as block devices or large system files, which can disrupt normal operations. | |||||
| CVE-2026-0967 | 2 Libssh, Redhat | 2 Libssh, Enterprise Linux | 2026-04-02 | N/A | 5.5 MEDIUM |
| A flaw was found in libssh. A remote attacker, by controlling client configuration files or known_hosts files, could craft specific hostnames that when processed by the `match_pattern()` function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion, resulting in a Denial of Service (DoS) for the client. | |||||
| CVE-2025-12801 | 2 Linux-nfs, Redhat | 3 Nfs-utils, Enterprise Linux, Openshift Container Platform | 2026-04-02 | N/A | 6.5 MEDIUM |
| A vulnerability was recently discovered in the rpc.mountd daemon in the nfs-utils package for Linux, that allows a NFSv3 client to escalate the privileges assigned to it in the /etc/exports file at mount time. In particular, it allows the client to access any subdirectory or subtree of an exported directory, regardless of the set file permissions, and regardless of any 'root_squash' or 'all_squash' attributes that would normally be expected to apply to that client. | |||||
| CVE-2026-5119 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-04-01 | N/A | 5.9 MEDIUM |
| A flaw was found in libsoup. When establishing HTTPS tunnels through a configured HTTP proxy, sensitive session cookies are transmitted in cleartext within the initial HTTP CONNECT request. A network-positioned attacker or a malicious HTTP proxy can intercept these cookies, leading to potential session hijacking or user impersonation. | |||||
| CVE-2026-28368 | 1 Redhat | 10 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Data Grid and 7 more | 2026-03-31 | N/A | 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-2026-28369 | 1 Redhat | 10 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Data Grid and 7 more | 2026-03-31 | N/A | 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-2024-7341 | 1 Redhat | 4 Build Of Keycloak, Enterprise Linux, Keycloak and 1 more | 2026-03-27 | N/A | 7.1 HIGH |
| A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation. | |||||
| CVE-2026-1801 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-03-26 | N/A | 5.3 MEDIUM |
| A flaw was found in libsoup, an HTTP client/server library. This HTTP Request Smuggling vulnerability arises from non-RFC-compliant parsing in the soup_filter_input_stream_read_line() logic, where libsoup accepts malformed chunk headers, such as lone line feed (LF) characters instead of the required carriage return and line feed (CRLF). A remote attacker can exploit this without authentication or user interaction by sending specially crafted chunked requests. This allows libsoup to parse and process multiple HTTP requests from a single network message, potentially leading to information disclosure. | |||||
