| CVE-2025-0243 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-13 | 5.1 Medium |
| Memory safety bugs present in Firefox 133, Thunderbird 133, Firefox ESR 128.5, and Thunderbird 128.5.

| CVE-2025-0240 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-13 | 4 Medium |

| CVE-2025-0239 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-13 | 4 Medium |
| When using Alt-Svc, ALPN did not properly validate certificates when the original server is redirecting to an insecure site. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Thunderbird 134, and Thunderbird 128.6. | ||||
| CVE-2025-0238 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-13 | 5.3 Medium |
| Assuming a controlled failed memory allocation, an attacker could have caused a use-after-free, leading to a potentially exploitable crash. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Firefox ESR 115.19, Thunderbird 134, and Thunderbird 128.6. | ||||
| CVE-2025-0237 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-13 | 5.4 Medium |
| The WebChannel API, which is used to transport various information across processes, did not check the sending principal but rather accepted the principal being sent. This could have led to privilege escalation attacks. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Thunderbird 134, and Thunderbird 128.6. | ||||
| 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-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-2025-26601 | 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. | ||||
| CVE-2025-26600 | 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 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 | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 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 | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 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 | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-04-06 | 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. | ||||
